The Silent Check Valve was designed to open at approximately ¼ to ½ psi (2-3 kPa). This means that when a pump is shut down, a Silent Check Valve will completely close while there is still positive head on the inlet side of approximately ½ psi (3 kPa). In this simple manner reverse flow, which is a major cause of water hammer, is prevented.

Right Angle Check Valves These valves allow free flow in one direction and prevent flow in the reverse direction. Cracking pressure specified is the pressure required to open the valve and allow free flow. Specifications Model Number Designation Model Numbers Rated Flow * L/min Max. Operating Press.

Series C check valves permit free flow in one direction, and dependable shut-off in the reverse direction. Operation When pressure going through the valve is increased to the cracking level, the valve opens. When the pressure is reduced to below the cracking level, the valve closes. Features • Stainless steel poppets standard.

The main purpose of the DUAL PLATE WAFER CHECK valve is to perform the work of almost any conventional valve. However, being smaller makes it lighter and, therefore, is more cost efficient to purchase, install and maintain. It is also a silent check valve; because of it's innovative design, it does not slam upon closing.

A Ball Check Valve consists of a threaded or flanged body with internal features that guide a rubber‐coated ball in and out of the seat as the flow goes forward and reverse. The ball rolls during operation and has a tendency to clean itself. The valve's top access port provides ease of maintenance without removal of the valve from the line.

Nov 11,  · As mentioned above, a check valve, also called a non-return valve, reflux valve, or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in one

Parker C Series Check Valves are designed for uni-directional flow control of fluids and gases in industries such as chemical processing, oil and gas production and transmission, pharmaceutical, pulp and paper, power and utilities. Flow Calculations with 1000 psig (69 bar) Inlet Pressure Valve Series Maximum C V Pressure Drop

ZRK-ZRKF-swing check valves are designed to block media on one side of the pipe within allowable pressure and temperature limits (see data sheet) and to be installed in a pipe system only. They are only to be used with media, which the material and the seals are resistant to. They are not suitable for media with solid components.

Series C check valves permit free flow in one direction, and dependable shut-off in the reverse direction. Operation When pressure going through the valve is increased to the cracking level, the valve opens. When the pressure is reduced to below the cracking level, the valve closes. Features • Stainless steel poppets standard.

valves are typically used in controlling the rate of decompression in a large press before shifting the main valve. Pilot operated valves, like direct operated valves, permit free flow in one direction and prevent flow in the reverse direction. However, pilot operated valves permit reverse flow when a pilot pressure signal is applied to the

FLANGED VALVES The DFT® Model PDC Check Valve. is a silent, non-slam check valve specially designed for use on the discharge side of reciprocating air or gas compressors. It includes a pulse-damping chamber to maintain the disc in the open position during the momentary reductions in flow associated with each cycle of a reciprocating

Easy Riser® Swing Check Valve, trim, and associated equipment. Prior to installing the valve, thoroughly flush the water supply piping to verify that no foreign matter is present. The Easy Riser® Swing Check Valve may be installed in the vertical position with direction of flow up, or in the horizontal position with the access cover up. 1.

Like the Basic-Check® valve, the Restrictor Check provides reliable, low maintenance service for a wide range of fluids and gases at various pressure/temperature combinations. The valve consists of a guard cage, spring, valve disc, retaining ring and seat.

Check valve Gate valve Globe valve Ball valve Valve shaped like a butterfly. Tight shut-off and can be used as a control valve. Little resistance to flow (allows smooth flow). Optimal for automated operation with a low operating torque and 90 degrees operating angle. Lightweight and compact (large diameter models are also available).
