Check Valves

Staitech HCV02, HCV04 and HCV05 check valves – designed specifically for high purity steam, liquid and gas duties in the pharmaceutical industry.

The Staitech HCV range comprises three models, all of which share a number of common design features:

Steel construction
316L stainless ASME BPE compliant clamp and weld connections
DIN and ISO sizes available
Low ferrite/low sulphur material options
Wetted surfaces finished to 0.5 microns Ra
Electropolished finish option
EN 10204:2004 3.1 Full component traceability
FDA and USP Class VI compliant body seal

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.

Size Range	3/4″ – 4″ ASME BPE compliant clamp fittings
Material	316L stainless steel
Opening Pressure	8, 35, 100 & 240 mbar
Options	Metal-metal and soft seat options Various seal materials
Literature	Data Sheet Installation & Maintenance

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.

Size Range	1/2″ – 4″ ASME BPE compliant clamp & weld connections
Material	316L stainless steel
Opening Pressure	8 & 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

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.

Size Range	3/4″ – 4″ ASME BPE compliant clamp fittings
Material	PTFE
Opening Pressure	8, 35, 100 & 240 mbar
Options	Wide range of seals – EPDM, Viton, Silicone & PTFE Soft seal seal
Literature	Data Sheet

The HCV04 range of check valves is ideally suited to steam, condensate and process fluid applications. Standard valves have metal-metal seating and a choice of 8 or 25 mbar opening pressure. A range of soft seat options are also available. Wetted surfaces on all valves are finished to 0.5 microns Ra. 1/2″ to 1″ valves are available in either standard or high capacity configuration.

Size Range	1/2″ – 4″ ASME BPE compliant clamp connections DN8-DN50 DIN & ISO clamp connections
Material	316L stainless steel
Opening Pressure	8 & 35 mbar
Options	Low ferrite stainless steel C22 and other alloys Metal-metal and soft seat options
