John Clark Valves (JCV) has come a long way since it was established in 1985, working from a small unit in Middlesbrough. Now operating out of its own premises in Stockton-On-Tees, JCV has become one of the UK's largest stockists of valves, carrying extensive ranges of gate, globe, check valves, ball valves, butterfly valves, wafer check valves and actuation. JCV operates within a quality controlled environment, which has been externally accredited by BSI to conform with the requirements of ISO 9001:2008.
