Forged Steel Flanged Gate Valve

Forged steel flanged gate valves are made by die forging and connect to pipelines through flanges. That forging process gives the valve a dense, strong body, so it can handle high pressure and tough conditions. 
Specific Applications
You will find these valves in petroleum, chemical, power, and metallurgical plants, especially on high‑temperature and high‑pressure small‑bore lines. Forged steel flanged gate valves cover pressure ratings from PN16 to PN756 and temperatures from -29°C up to 800°C.
Key Features
High-Strength Forged Construction – Die‑forged body provides a dense, defect‑free grain structure. Available in A105, Stainless Steel 304, F11, F22, F316. Built to handle high pressure (PN16 to PN756) and high temperature (‑29°C up to 800°C).
API 602 & Class800 Ready – Designed to API 602 standards. Rated up to Class800 and beyond. Perfect for petroleum, chemical, power, and metallurgical plants – especially small‑bore, high‑pressure lines.
Three Bonnet Options for Zero Leakage – Bolted bonnet (easy repair with a spiral‑wound gasket), welded bonnet (fully sealed, no external leak), or pressure‑seal bonnet (tighter as pressure rises). You choose based on your service.
Durable Stem & Sealing – Stem is heat‑treated and nitrided for corrosion and galling resistance. Force‑sealed design with gate perpendicular to flow – reliable shut‑off for on‑off duty.
Flexible Flanged Connections & Standards – For this Forged Steel Flanged Gate Valve, flanged ends to DIN, ANSI, JIS, BS, or GB. Every valve is pressure tested, seat leak tested, and visually inspected before shipment.
Quality Certification
We hold ISO 9001, ISO 14001, and ISO 45001 certifications, plus a special equipment production license (TS). Our products are made to API, ANSI, JIS, ISO, BS, JB, and GB standards. This covers material checks, non‑destructive testing, precise measurements, and valve strength/sealing performance.
Custom Manufacturing Services
You send us a drawing or sample, and we review the requirements. Then we confirm the drawing and give you a quote — faster if you provide a 3D model. After order confirmation, we schedule batch production.
