Sigma Valves Company Profile

OUR COMPANY

Sigma Valves began producing stainless steel pneumatic and hydraulic control valves dedicated specifically for the oil and gas industry over forty years ago. Sigma Valves originated as a company dedicated to valves specifically designed for safety system automation in offshore environments, not industrial valves converted for use in the oil/gas industry. These valves offer more robust design features and dependability than those found in smaller industrial-type valves.

Our current range of products includes: manual reset relays, quick exhausts, fusible valves, check valves, LPO kits for actuation, Hydraulic interface valves, pressure sensors, regulator, accumulators and other components for control system fabrication.
