The BiS range of inline check valves is a comprehensive range comprising nominal bore sizes from 1/4” to 2”. Manufactured from stainless steel, they are suited to use with a wide range of liquids and gases, with pressures up to 1379 bar (20,000 psi). High cracking pressure check valves are also available by contacting the factory. In addition, there are cartridge check valves for use in manifolds or for direct integration into other equipment. The SV range of shuttle valves may be selected when it is necessary for a valve to select the higher of two pressures, a function often used when redundancy of pilot systems is required.
