Constant-Pressure Modulating Valve

The Constant-Pressure Modulating Valve is manufactured directly by Shanghai Ansha Fluid Technology Co., Ltd. to regulate piping-system pressure via compressed air, operating in either an inlet-pressure-holding mode (used as an overflow valve behind actuators or heat exchangers) or an outlet-pressure-holding mode (used for liquid filling and bottling machines). It is available in DN25-DN50 (1.0"-2.0") sizes, rated for 0-1.0 MPa operating pressure and -20C to +135C depending on seal material, constructed in 316L (media-contact parts) and 304 (non-contact parts) with PTFE+EPDM seals as standard, and supports welding, tri-clamp, flange, and thread connections to DIN11850, 3A, and ISO1127 standards. The manufacturer distributes it worldwide.
