FAQ

Frequently Asked Questions

What does 1000 WOG mean?

WOG stands for water, oil, gas. A 1000 WOG valve is rated for 1000 psi (about 69 bar) cold working pressure on those media. The allowed pressure falls as the temperature rises.

Which thread does this valve have?

This valve has male NPT threads. Our 2-piece female threaded valve has BSPT threads as standard.

Male or female threads: which do I need?

Male ends screw into a female fitting or port; female ends take a male pipe nipple. For female ends see our 2-piece female threaded ball valve.

What documents ship with the valve?

A product test report and an EN 10204 3.1 material certificate for the lot. We welcome third-party inspection (e.g. SGS or BV), arranged and paid for by the buyer.

What is the lead time?

Standard sizes ship in 15–20 days from stock. Special materials or options may take longer; we confirm the delivery date with your quote.
