Cast steel gate valve, os&y, rising stem

This cast steel gate valve complies with ASME B16.34 and API 600 standards, featuring an outside screw and yoke with rising stem, bolted or pressure seal bonnet, and a flexible wedge design. It is rated for pressures from 150lb to 2500lb and sizes ranging from 2 to 48 inches. The valve includes an extended bonnet option for cryogenic service and a bypass port available on request, with locking devices offered as an optional feature.

The body and internals are manufactured from carbon steel or alloy steel grades suitable for high-pressure industrial use. The seat is replaceable, and the flexible wedge ensures tight shutoff under varying pressure conditions. These valves are typically used in oil and gas, power generation, and chemical processing where leak-tight isolation is critical. Standard materials conform to ASTM A216 WCB or equivalent, with no indication of stainless steel or exotic alloy options in this listing.

Buyers in industrial maintenance, EPC contractors, and pipeline operators source these valves for critical service applications requiring full port flow and reliable shut-off. Packaging is typically wooden crate with internal foam padding. Trade terms are FOB Zhejiang port, lead time is 30 to 45 days after deposit, and minimum order quantity is confirmed only upon direct inquiry. Documentation includes mill test reports and pressure test certificates as standard.
