Description du produit<\/h2>\n

The J41W-200R is a threaded stainless steel gate valve in cast 316 (ASTM A351 CF8M), rated 200 WOG (200 psi), sizes 1\/2\u2033 to 2\u2033 with female PT (taper pipe) threads. Turning the handwheel raises or lowers a solid wedge gate \u2014 when fully open the gate clears the bore completely, so flow is unrestricted and pressure drop is near zero.<\/p>\n

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 \u2014 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.<\/p>\n
