- Poppet valve & components, including valve stem oil seal. The yellow paint is a spring strength marking. A poppet valve (also called mushroom valve) is a valve typically used to control the timing and quantity of gas or vapour flow into an engine.It consists of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem.The portion of the hole where the plug meets with it is referred as the 'seat' or ' valve seat '.t consists of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem.

Plug valve The simplest and most common general type of plug valve is a 2-port valve with two positions: open to allow flow, and shut (closed) to stop flow. Ports are openings in the valve body through which fluid can enter or leave.

- The second valve, TAD (Thermactor Air Diverter valve or AM2 valve) directs it to the heads or the catalytic converters. Check valves located after the TAB & TAD solenoids prevent hot exhaust gases from damaging the control valves or pump in case of a backfire.he smog pump puts air into the heads when the engine is cold and then into the catalytic converters when it is warm. The Thermactor control valves serve to direct the flow. The first valve, TAB (Thermactor Air Bypass) or AM1 valve) either dumps air to the atmosphere or passes it on to the second valve.

- Differential dry pipe valves use the principal of a lower air pressure on the top of the clapper holding back a higher water pressure below the valve. The way this is accomplished in many valves is to build the valve with a large clapper that covers two seats. The inner ring is the water seat in the middle of the valve; A dry pipe sprinkler valve is a special valve that prevents the pressurized water in the fire mains from entering the sprinkler system piping. Normally, this is accomplished by filling the system with air. Most valves use a differential method of keeping the valve shut, and generally, the differential is 5:1 or 6:1. This

Diaphragm Valves Information A diaphragm valve is a linear motion valve that is used to start/stop and control fluid flow. Method Of Control . Diaphragm valves use a flexible diaphragm connected to a compressor by a stud which is molded into the diaphragm. Instead of pinching the liner closed to provide shut-off, the diaphragm is pushed into contact with the bottom of the valve body to provide shut-off.

- POST INDICATOR VALVES The Post Indicator Valve or PIV, comes in several types. The PIV is used when the main valve body in not visible (underground, behind/other side of wall). These valves are typically used for isolating sections of piping or hydrants. Yet they can also be used for sprinkler risers. What makes these valves unique is the window.

Check valve 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. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. duckbill valve is a check valve in which flow proceeds through a soft tube that protrudes into the downstream side. Back-pressure collapses this tube, cutting off flow. A pneumatic non-return valve. Multiple check valves can be connected in series.

- More About Gate Valves. A gate valve is a type of valve used to prevent the flow of liquid in a plumbing system. It is primarily designed to be completely open or completely closed. Consequently, gate valves are rarely used as a means of regulating flow.A standard gate valve has a bonnet found on top of the valve body. gate valve is a type of valve used to prevent the flow of liquid in a plumbing system. It is primarily designed to be completely open or completely closed.

- opening the hydraulic circuit. The outside of the armature tube and the valve body are zinc coated for surface protection. FUNCTION The pressure tight switching solenoid and in turn the spring on the opposite side shift the guided poppet into an either open or closed position. Due to the equal-area- and balanced- poppet-design there are no undesired opening or closing forces. Fluid may pass the poppet valve in both directions. The poppet piston is sealed by an o-ring. The seat with metallic seal closes leak free in both directions. APPLICATION Wandfluh solenoid operated poppet valves are applied where an absolutly leak free closing of the valve is essential like in load holding, clamping or gripping functions. The solenoid

Check valve 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. There are various types of check valves used in a wide variety of applications.Check valves are often part of common household items. ball check valve in the open position to allow forward flow and closed position to block reverse flow. A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a spherical ball. In some ball check valves, the ball is spring-loaded to help keep it shut.

Blowoff valve A compressor bypass valve (CBV), also known as a pressure relief valve or diverter valve, is a manifold vacuum-actuated valve designed to release pressure in the intake system of a turbocharged vehicle when the throttle is lifted or closed. blowoff valve is connected by a vacuum hose to the intake manifold after the throttle plate. When the throttle is closed, the relative manifold pressure drops below atmospheric pressure and the resulting pressure differential operates the blowoff valve's piston.

- Organ pipe. An organ pipe is a sound-producing element of the pipe organ that resonates at a specific pitch when pressurized air (commonly referred to as wind) is driven through it. Each pipe is tuned to a specific note of the musical scale. A set of organ pipes of similar timbre tuned to a scale is known as a rank or a stop.
