Ball Valve
Valve: Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Ball Valve: A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball’s hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. Ball Valve is a Shutoff type valve which is used to control the flow of Fluid (Liquid/Gas). The valve basically has ball inside it which is used to control the flow, the ball is attached with an external lever which opens/closes the passage for fluid to pass through the valve. Usually ball valves are used for sizes below 100MM, above that gate valves are used instead of ball valve. Ball valves comes in various type and in various MOC
Air Release Valve
Valve: Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Air Release Valve: Air Release Valves, or Air Relief Valve function to release air pockets that collect at each high point of a full pressured pipeline. An air release valve can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure.
Relief Valve
Relief Valve: A relief valve or pressure relief valve is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire.
Safety Valve
Valve: Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Safety Valve: A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve, which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits.
Diaphragm Valve
Valve:Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Diaphragm Valve: Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, an elastomeric diaphragm, and a “weir or saddle” or seat upon which the diaphragm closes the valve. The valve body may be constructed from plastic, metal, wood or other materials depending on the intended use.
Check Valve
Valve: Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Check Valve: A check valve, clack valve, non-return valve, reflux valve, retention valve or one-way valve is a valve that normally allows fluid to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.
Ferrule Cock
Ferrule Cock: Ferrule Cocks incorporate a packed gland spindle and have a union outlet for connection to all ferrule bends or adaptors. RMC TPFNR Ferrules are for under pressure tapping. They incorporate a non-return gunmetal jumper valve and a high-density polyethylene tapered closing plug.
Knife Edge Valve
Valve: Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Knife Edge Valve: Knife Edge Valve are designed mainly for on-off and isolation services in systems with high content of suspended solids. The knife gate valves are especially beneficial for handling slurry, viscous, corrosive and abrasive media. The valves have a minimized pressure drop in fully open position, they are easy to actuate, they have a relatively low weight and are cost effective.
Knife Edge Valve are designed to work in some of the most harsh environments, typically having a sharpened blade to cut through heavy liquids.
Globe Valve
Valve: Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.,
Globe valve: A globe valve is a linear motion valve used to stop, start, and regulate the fluid flow. The globe valve disk can be removed entirely from the flow path, or it can completely close the flow path. During opening and closing of globe valve, disc moves perpendicularly to the seat.
Non Return Valve
A non-return valve is a simple mechanical device that is used to allow a medium pressure flow in any one direction. It helps the fluid to travel with a medium velocity in one direction and prohibits the reverse flow of the fluid caused by very high pressure. The non-return valves cause a very high-pressure drop which is a drawback for it. it also helps to prevent the upstream types of equipment that could get damaged by reverse flow such as water pumps. They are also known as check valves. The non-return valves are available in various types such as clapper type, swing type, spring-loaded, etc. they could be manually operated or also by automated actuation.
Bonnet Wheel Valve
Bonnet Wheel Valve: The cover for the opening sin the body is the bonnet, and it is the second most important boundary of a pressure valve. Like valve bodies, bonnets are in many designs and models available. A bonnet acts as a cover on the valve body, is cast or forged of the same material as the body. It is commonly connected to the body by a threaded, bolted, or welded joint. During manufacture of the valve, the internal components, such as stem, disk etc., are put into the body and then the bonnet is attached to hold all parts together inside.
Stop Valve
Stop Valve: Stop valve is any sort of valve type that completely stops the flow of liquid flow through a pipe. Stop valves is mainly used in plumbing or industrial applications to shut off the flow of (hot or cold) water to a plumbing fixture, such as an icemaker, toilet, faucet, dishwasher etc.
Foot Valve
Valve: Valves are for starting or stopping flow, regulating or throttling flow, preventing back flow or relieving and regulating pressure in fluid or gaseous handling applications. Common valve types include: Ball, Butterfly, Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc.
Foot Valve: A foot valve is a type of check valve that is typically installed at a pump or at the bottom of a pipe line (hence the name). Foot valves act like ball check valves, but have an open end with a shield or screen over it to block debris from entering the line.
Fusible Plug
Fusible Plug: A fusible plug operates as a safety valve when dangerous temperatures, rather than dangerous pressures, are reached in a closed vessel. In steam engines the fusible plug is screwed into the crown sheet (the top plate) of the firebox, typically extending about an inch (25mm) into the water space above it.
Butterfly Valve
Butterfly valves are very similar to ball valves they also work on the phenomenon of quarter-turn rotational movement which means by moving 90 degrees it could be either turned on to fully operated or turned off to restrict the flow of fluid. This is used to transfer, regulate or stop the movement of a fluid. They are used widely in the industries such as food processing, water supply industries, water pumping, etc. they are used wherein there is a need for a broad range of flow isolation Is required. “They belong from the quarter-turn family” and they usually have large pipe diameter.
Needle Valve
Needle Valve: A needle valve is a type of valve with a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, although it is generally only capable of relatively low flow rates.
Fire Hydrant Landing Valve
Fire Hydrant Landing Valve: A Fire Hydrant Valve is a pipe fitting that help to regulate, direct or control the flow of fire suppressing agents by opening, closing or partially obstructing passageways in the hose connectors. Non-return valves stop the fire suppressing agent from flowing in the wrong direction.
Gauge Cock
Gauge Cock: Gauge Cocks provide an economical way to shut off the flow of air to the pressure instrument, thereby allowing the instrument to be isolated from the pressure media or removed from service. Gauge Cocks are constructed from brass and are intended for use on air lines where leakage is not of concern.
