Product Description
A 1000 WOG one-piece stainless steel ball valve with a welded body, in 304 or 316. PTFE seats, PT taper threads, manual quarter-turn lever. Two end configurations: female × female (F×F) from 1/4″ to 3″, and male × female (M×F) in 1/4″, 3/8″ and 1/2″.
Because the body is welded instead of bolted, there is no threaded body joint — one fewer place for the valve to leak. The trade-off is that it cannot be opened for service. We say so plainly further down, and we point you at the valve you should buy instead.
What 1000 WOG Actually Means
WOG stands for Water, Oil, Gas. A 1000 WOG rating means the valve is rated for 1000 psi of cold, non-shock working pressure on those three media.
Two things buyers get wrong about it:
- WOG is a cold rating. It is not a steam rating, and it says nothing about how the valve behaves hot. Tell us the temperature of your line and we will confirm the valve suits it.
- “Non-shock” is part of the rating. A line with water hammer or rapid pump starts sees pressure spikes well above its normal working pressure. Size for the spike, not the gauge reading.
If your line runs above 1000 psi cold, this is not the valve — tell us the pressure and we will quote the right one.
F×F or M×F — Which One Do You Need?
- Female × Female (F×F) — both ends take a male pipe or fitting. The general-purpose choice, and the only one available above 1/2″ (up to 3″).
- Male × Female (M×F) — one male end screws straight into a female port, so you save a fitting and shorten the assembly. Available in 1/4″, 3/8″ and 1/2″ only.

Where It Belongs
- Instrument and gauge lines — compact shut-off ahead of pressure gauges and transmitters.
- Water, oil, gas and air — general utility shut-off up to 1000 WOG.
- OEM machinery — a small valve that fits inside a machine frame or a skid.
- Tight installations — where a two-piece or three-piece body will not fit.

FAQ
What does 1000 WOG mean?
WOG stands for Water, Oil, Gas. A 1000 WOG rating means the valve is rated for 1000 psi of cold, non-shock working pressure on those media. It is not a steam rating, and it says nothing about the valve hot — tell us your line temperature and we will confirm the valve suits it.
What sizes are available?
Female × female (F×F) from 1/4″ to 3″. Male × female (M×F) in 1/4″, 3/8″ and 1/2″. Dimensions for 1/4″ to 2″ are in the table on this page; 2-1/2″ and 3″ are stocked and we will send you the dimensions on request.
Which thread standards do you supply?
PT (taper) thread from stock. NPT and PF are made to order.
Can this valve be opened for cleaning or repair?
No. The body is welded, so it cannot be taken apart. That is the trade-off for having no threaded body joint to leak. If you need to service the valve in line, buy the three-piece ball valve instead.
Is this a full port valve?
No. It is a standard (reduced) port valve — the bore is smaller than the pipe. If you need full bore flow, buy the two-piece full port valve.
Can I mount an actuator on it?
No. This body has no actuator mounting pad. If you need automation, buy the pneumatic ball valve.
304 or 316 — which should I order?
316 wherever chlorides are present: brine, seawater, coastal air, most chemical service. The molybdenum in 316 is what resists chloride pitting. 304 for general water, air and oil duty.
Can you supply a material certificate?
Yes. A mill certificate is available on request.
Do you have a minimum order quantity?
No. Tell us what you need and we will quote it.
