DESIGN STANDARDS

The stainless steel valve body ensures nonporous, smooth surfaces and dimensionally stable construction. The valve body is in two parts, assembled by means of a clamp and sealed with a gasket. The self draining design of the lower valve body enables flushing of the product. Ribbed construction of the stainless steel disc resists heavy pressure hammer, minimize the resistance to flow and also serves as a guide to the valve plug. All seats and seals are made from FDA approved materials.

APPLICATION

Check valve, also known as “non-return valve”, is designed for use in process piping installations to prevent reverse flow.

MATERIAL

Product wetted steel parts : AISI 304 or AISI 3 l 6L
Other steel parts : AISI 304
0 ring and gasket : EPDM, comply with FDA21 CFR 177 .2600
Options :

– 0 ring and gaskets can be Silicone or Viton, all complying with FDA 21CFR177.2600.

– Connection ends: Butt-welded, Sanitary Tri-clamp, Threaded or others upon request.

WORKING PRINCIPLE

A check valve opens when the pressure below the valve plug exceeds the pressure above the valve plug and the spring force. The valve close when pressure equalization has been achieved.
