HCV01 & HCV01B

The HCV01 check valve is designed to fit between two ASME BPE compliant clamp fittings, sealing on the ID of the tube using FDA approved EPDM O-rings. The compact 316 stainless steel design is suitable for a wide range of duties in steam, liquid and gas service, including pressure relieving and anti-vacuum applications. Standard valves have metal-metal seating. A number of soft seal and spring options are also available.

HCV02

The HCV02 range is intended for use in high purity applications such as WFI systems. Valves are manufactured in 316L stainless steel with a range of seal options. Wetted surfaces are finished to 0.5 microns Ra. The standard opening pressure for the HCV02 range is 35 mbar. Where a valve is to be installed in a horizontal line and drain-ability maintained, then the HCV02E eccentric version is available.

Applications	Process flow control Back flow prevention
Size range	1/2″ – 4″ ASME BPE compliant clamp & weld connections
Material	316L stainless steel
Opening pressure	8 or 35 mbar
Options	Wide range of seals – EPDM, Viton, Silicone & PTFE DN8-DN50 DIN, ISO clamp & weld connections available Concentric & eccentric designs Low ferrite and low sulphurs stainless steel grades C22 alloy and other materials Enhanced surface finishes and electropolishing

HCV03

The HCV03 check valve is designed to fit between two ASME BPE compliant clamp fittings, with a moulded seal profile replacing the standard joint gasket. The valve is suitable for a wide range of duties in liquid and gas service, including pressure relieving and anti-vacuum applications. A number of soft seat seal and spring options are also available.

Applications	Process flow control Back flow prevention
Size range	3/4″ – 4″ ASME BPE compliant clamp fittings
Material	PTFE

HCV05 weld connections

The HCV05 check valve is now available in sizes up to 2″ with weld end connections in low Sulphur 316L material. For more information please contact Staitech.

6″ non return valve

Staitech have recently supplied a number of 6″ check valves suitable for ASME BPE tubing. The valves incorporate a double-flap cartridge design to ensure minimum pressure drop. All metal contact parts are 316/316L stainless steel with FDA compliant Gylon seals. Contact Staitech for further information.
