Dimensions
Dimensions (mm)
The dimension drawing for each size (DN8 to DN100) is sent with your quotation, so you can check face-to-face length and thread before ordering.
FACE-TO-FACE CHECK
QC TAG ON EVERY VALVEChecked before packing
Thread gauges and face-to-face length are checked before packing. Each valve is pressure-tested for shell and seat leakage.
Pressure rating
Pressure Rating
| Rating | Cold working pressure |
|---|---|
| 1000 WOG | 1000 psi (about 69 bar) |
Cold, non-shock working pressure on water, oil and gas. The allowed pressure falls as the temperature rises; the PTFE seat sets the limit of +150 °C.
Testing
Pressure Test on Every Valve
| Test | Pressure |
|---|---|
| Shell test | Every valve |
| Seat test | Every valve |
Actual test pressures for each lot are on the test report.

FAQ
Frequently Asked Questions
Why choose a 3-piece ball valve?
The centre body is held between two end pieces by bolts. Remove the bolts and the centre body swings out, so seats and seals can be replaced while the end pieces stay threaded on the pipe.
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 female BSPT threads; the thread is marked on the order confirmation.
Is a 2-piece valve cheaper?
Yes. If the valve does not need in-line service, our 2-piece female threaded ball valve costs less.
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.
