Our safety valves are certified by the National Board as manufactured, assembled and stamped in accordance with the construction code: ASME Section VIII, Division 1: UV stamp. They are also certified with the Canadian Registration System for Pressure Vessels, piping systems, and fittings. Each valve is stamped with a CRN number.
Copies of certificates available on request.

Valves are also available with nickel electroplating for use in sour environments, in hard seat (metal to metal) and stainless steel construction by special order.
