صمام بوابة ملولب يدوي – فولاذ مقاوم للصدأ 316 (CF8M)، 200 WOG، سلسلة GT

وصف المنتج

The J41W-200R is a threaded stainless steel gate valve in cast 316 (ASTM A351 CF8M), rated 200 WOG (200 psi), sizes 1/2″ to 2″ with female PT (taper pipe) threads. Turning the handwheel raises or lowers a solid wedge gate — when fully open the gate clears the bore completely, so flow is unrestricted and pressure drop is near zero.

A gate valve is the right choice where a valve stays fully open or fully closed for long periods and a clear, full bore matters — unlike a ball valve, the multi-turn handwheel closes slowly, which avoids the water hammer a fast quarter-turn can cause. Body, cap, disc and stem are 316 stainless with a PTFE gasket and V-ring packing, tested to API 598 and designed to ANSI B16.34.

المزايا والفوائد

• Full clear bore: the gate lifts completely out of the flow path, so an open valve adds almost no pressure drop.
• No water hammer: the multi-turn handwheel closes slowly, avoiding the pressure surge a fast-closing valve can cause on long liquid lines.
• 316 stainless throughout: CF8M body and 316 stem resist corrosion in water, marine and chemical service.
• API 598 tested: every valve is shell- and seat-tested before shipment.

مجالات التطبيق والمواقع

• Plumbing & utility mains: isolation points that stay fully open or closed for long runs.
• معالجة المياه & distribution: full-bore isolation with low pressure drop.
• Oil, gas & process lines: on/off isolation where a clear bore is required.
• Building services: riser and equipment isolation valves.

الأسئلة الشائعة

Gate valve or ball valve — which should I use? A gate valve gives a fully clear bore and closes slowly with a multi-turn handwheel, so it avoids water hammer — best where the valve stays open or closed for long periods. A ball valve is a fast quarter-turn on/off. For threaded ball valves, see our stainless steel valve range.

What size and pressure is it? Sizes 1/2″ to 2″ (DN15–DN50), rated 200 WOG (200 psi). Body and disc are cast 316 stainless (CF8M).

Which thread does it use? Female PT (taper pipe) thread. Tell us the size when you request a quote.

What is the operating temperature? -20 °C to +190 °C, with the PTFE packing and gasket setting the practical limit.

Is it tested? Yes — designed to ANSI B16.34 and tested to API 598 (shell 2.0 MPa, seat 1.6 MPa) before shipment.
