Sanitary constant pressure valve

HY2 valve is sanitary constant pressure valve, which used in stainlee steel pipeline system.
HY2-1(Constant-Pressure Modulating inlet) maintain a constant pressure in the process line at the inlet side of the valve. Typical applications of HY2-1 are after separators, heat exchangers etc. and as overflow valves.
HY2-2 (Constant-Pressure Modulating Outlet) maintains a constant pressure in the process line at the outlet side of the valve. Typical applications of HY2-2 are before filling/bottling machines etc.

Detailed Description

HY2 are remote-controlled by means of compressed air. The valves operate without a transmitter in the product line and require only a pressure regulating valve for the compressed air and a pressure gauge in the product line.
HY2-1 open at increasing product pressure and vice versa.
HY2-2 closes at increasing product pressure and vice versa.
