What is a Forged Gate Valve?
A forged-body gate valve isolates the flow using a sliding gate / wedge in full open–close service. The homogeneous grain structure of forged steel increases mechanical strength under high pressure and temperature. In the fully open position, the flow path is wide and pressure loss is low. In tight spaces, the forged gate valve provides secure isolation with a compact body, helping to optimise maintenance intervals.
The EMS Valve Assurance
EMS Valve operates with a corporate quality system that puts process safety at the centre. From design to shipment, traceability, documentation and inspection steps are all tied to clear procedures. In this way, technical compliance and operational sustainability are delivered together in the supply of forged valves. Post-purchase support and spare parts management are also handled centrally and in a planned manner.
Standards and Design Principles
Typical design references for the Forged Gate Valve include API 602 (compact forged valves) and ASME B16.34 (pressure–temperature ratings), while leakage tests are performed in accordance with API 598. Face-to-face dimensions in the compact class follow ASME B16.10.
The body–bonnet connection is selected as bolted bonnet, welded bonnet or pressure seal depending on the application. OS&Y (Outside Screw & Yoke) and rising stem construction make maintenance access easier and provide clear visual indication of valve position.
End Connection and Material Options
Depending on the line requirements, end connections can be configured as SW (ASME B16.11), BW (ASME B16.25), NPT/BSPT (ASME B1.20.1) or RF flanged (ASME B16.5) on request.
Body materials cover carbon / low-temperature steels (A105, A350 LF2), stainless steels (A182 F304 / F316) and extended high-temperature grades. Seat surfaces can be specified with metal-to-metal sealing and cobalt-based hardfacing options.
Handwheel operation is standard; for high torque requirements or remote operation, integration of gearbox, pneumatic or electric actuators is available. Sizing of the gate valve and actuator combination is carried out considering required torque, operating cycle frequency and emergency scenarios.
Applications and Performance
n refineries, petrochemical plants, power stations and chemical facilities, the Forged Gate Valve is preferred for on/off isolation duties. The full-bore flow profile in the fully open position can contribute positively to pump energy consumption.
Stability under thermal shock and vibration is enhanced through appropriate packing selection (e.g. graphite) and optimised mating surfaces. The forged gate valve also provides reliable shut-off in viscous or particle-laden media.
