CRP check valves give long service

A fully PFA encapsulated one-piece disc/hinge assembly ensures that the new STCV check valves from CRP Flex-Rite give long maintenance-free service, even in the most demanding of operating conditions

A fully PFA encapsulated one-piece disc/hinge assembly ensures that the new STCV check valves from CRP Flex-Rite give long maintenance-free service, even in the most demanding of operating conditions.

The retained-hinge design of the new valves, which are suitable for use with PTFE-lined or unlined pipework, ensures that the disc cannot become detached during installation or in service, unlike other designs which rely on the pipe-work mating flanges to hold a loose assembly in place.

Developed specifically to meet the requirements of chemical and petrochemical industry applications involving severe process conditions, STCV high-integrity PFA lined wafer swing-check valves also feature an angled seat design that ensures positive location in horizontal lines which makes this valve uniquely suitable for either horizontal or vertical installation.

Machined body T-slots and a patented liner locking system ensure that the liner is retained securely in place.

To allow visual confirmation of integrity, as an additional safeguard to the physical product testing, both the liner and the disc/hinge assembly are manufactured from virgin PFA with no pigmentation, which might conceal defects.

Available in versions to suit pipework with diameters from 100mm to 300mm, the CRP Flex-Rite STCV swing check valves are supplied, as standard, with cast-steel bodies.

The valves are suitable for use at pressures from -1 bar up to +19 bar over a temperature range -29C up to +200C dependant on the process conditions.
