Materials and standards

Body: CF8M (A351) or 304; ball: 316 with mirror finish; seats: PTFE / RPTFE; stem: 316 with anti-static device; pressure rating 1000 PSI WOG (PN63); temperature -20 °C to +180 °C; threads NPT, BSPP or BSPT to ISO 228 / ANSI B1.20.1; testing per API 598 and EN 12266-1. All wetted parts are traceable to EN 10204 3.1 mill certificates, and each valve is pressure-tested before packing.

Frequently asked questions

Can the valve be actuated automatically?
Yes. Every body with a platform accepts our pneumatic actuator through an ISO 5211 mounting pad, and a limit-switch box or solenoid valve can be added for automated duty.

Which thread standard should I order?
NPT for North American piping, BSPP (G) for most European and CIS installations and BSPT (R) for tapered sealing joints. Mixed-end valves are available on request.
