SCA-X SS are check and stop valves in stainless steel with a built-in stop valve function. SCA-X SS are available in angleway versions. The valves are designed to open at very low differential pressures, allow favourable flow conditions and are easy to disassemble for inspection and service. SCA-X are equipped with vented cap and have internal backseating enabling the spindle seal to be replaced whilst the valve still under pressure.
