1/2″-2000PSI SS Close Die Forged Gate Valve
Description
TECHNICAL DATA SHEET
Product Name: 1/2″ 2000PSI Stainless Steel Close Die Forged Gate Valve
Model / Type: [Insert Model Number Here, e.g., Z11H/Y-2000P]
1. 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.
2. Key Features
-
Forging Process: Close-die forged body ensures a complete metal grain structure, free from casting defects, offering superior pressure-bearing capacity.
-
Disc Design: Features a rigid or flexible wedge design for reliable sealing.
-
Seat: Integral seat with hardfacing (Stellite) or precision machined seat (depending on configuration).
-
Stem: 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.
