1/2″-2000PSI SS Close Die Forged Gate Valve

TECHNICAL DATA SHEET

Product Name: 1/2″ 2000PSI Stainless Steel Close Die Forged Gate Valve

Product Description

This product is a high-pressure forged gate valve manufactured from high-quality stainless steel forgings. The body is formed through a precision close-die forging process, resulting in a dense structure, excellent grain flow, and high strength. It is designed to isolate or connect media in pipelines and is widely used in high-pressure systems across the petroleum, chemical, power, and metallurgical industries.

주요 특징

Forging Process: Close-die forged body ensures a complete metal grain structure, free from casting defects, offering superior pressure-bearing capacity.
디스크 디자인: Features a rigid or flexible wedge design for reliable sealing.
좌석: Integral seat with hardfacing (Stellite) or precision machined seat (depending on configuration).
줄기: Stainless steel with double-start threads, precision-rolled and polished for low operating torque.
Connection Type: Typically Threaded (NPT) or Socket Weld (SW) ends.
Fire Safe / Anti-static: Available options to meet API 607/6FA fire safe standards and include anti-static devices.
