API Gate Valves are high-integrity isolation valves manufactured strictly according to American Petroleum Institute specifications (API 600 for bolted bonnet cast steel valves, API 602 for compact forged steel valves, and API 6D for pipeline through-conduit gate valves). Built with heavy-duty corrosion allowances, precision guided wedges, and API trim configurations, API gate valves are the primary standard for hydrocarbon extraction, crude refineries, petrochemical skids, and natural gas transmission.
Zeron Fastners manufactures API Gate Valves in Class 150# through Class 2500# in sizes 1/2" to 48". Engineered in ASTM A216 WCB, A352 LCC, A105, and Duplex Stainless Steels with API Trim #1, #5, #8, and #16. 100% inspected and certified under API 598 and API 6D testing protocols.
