Wafer type check valve

RITAG Type ZRK and ZRL-HG wafer type swing check valves RITAG Type ZRK is used most commonly in pipe systems for industrial applications of all kinds. These wafer type swing check valves are virtually maintenance free. The seat seal can be an elastic or a metal to metal seal.

In other words, the wafer version of butterfly valves was designed to hold a tight seal, safeguarding against bi-directional pressure differential in order to avoid any backflow in systems that have been. When it comes to check valves, swing checks and wafer checks are actually similar in many ways. Both serve to block back flow from occurring in a pipe line.

Both use a swinging disc to block and allow flow in one direction. A check valve , clack valve , non-return valve , reflux valve , retention valve or one-way valve is a valve that normally allows fluid (liquid or gas) 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. One of the most comprehensive valve product lines available from any manufacturer.

From the most common application to the most severe, Velan has a solution. This design minimizes prospective leak paths through the valve body making it a preferable option for highly toxic, corrosive, or hazardous gas chemical processing applications. Keckley wafer body double disc check valves are also suitable for liqui natural gas, steam service, and vacuum service applications.

A check valve is a backflow prevention device: it allows flow in only one direction. The pressure of forward fluid flow opens the valve disc and the pressure from backflow closes it, forcing the disc against the valve seat.

Wafer Valve Wafer Valve. Three types of check valves are available to achieve this checking effect. What is the difference between check valve and nonreturn valve? What are the different type of check valves?

Where is my check valve? What does the check valve on a faucet do? Similar in operation to a swing check valve , the wafer check has a solid thermoplastic disc and seat arrangement that performs the. The Keckley retainerless wafer lug body double disc check valve features a single cast body without pin retainer holes in the body.

MVS single plate swing type wafer check valve comes with a short pattern sandwich type flangeless wafer body conforming to the API 6D and ASME B 16. The valve has a simple but reliable and robust construction. The wafer check valve is ideal for pump discharge duties.

The eccentric mounted hinge pin. This check valve is cast iron and face-to-face according to MSS-SP126. Maric Flow Control Valves are available in wafer types to suit a wide range of flange specifications i. Australian, American ANSI, British BS, and numerous other specifications.

Our elastomer hinge check valve design takes performance to an entirely new level by eliminating the restrictive valve seat and substantially increasing the valve ’s open area and flow coefficient (Cv).
