Electric Pressure Sealed Gate Valve

Product Overview

The Electric Pressure Sealed Gate Valve combines robust pressure-sealing technology with intelligent motorized actuation for fail-safe isolation in extreme-pressure applications. Engineered for ASME Class 900–4500 systems, this valve delivers zero-leak performance in power plants, offshore platforms, and hydrocarbon processing where manual operation is hazardous or impractical.

Key Technical Specifications

Core Advantages

Pressure-Energized Sealing

Motor operators with torque sensing & position feedback enable remote control via PLC/DCS integration.

• Optional fail-safe spring return for emergency shutdown (ESD) compliance.

Extreme Environment Ready

• Non-rising stem design prevents debris ingress in buried/offshore installations.

• Stellite 6 hard-faced seats withstand abrasive/cavitating flows.

Key Applications

The Electric Pressure Sealed Gate Valve is indispensable across industries relying on high-temperature fluid control:

Power Generation: Installed in boiler feedwater lines, steam turbines, and cooling systems to handle high-temperature steam and protect turbine components;

Petrochemical Refining: Used in distillation columns, cracking units, and hydrocarbon transfer lines to manage hot, corrosive crude oil byproducts;

Chemical Manufacturing: Ideal for heat-intensive reactions (e.g., polymer production) and handling hot chemical solvents, acids, or alkalis;

Oil & Gas Upstream/Downstream: Suitable for wellhead steam injection systems (enhanced oil recovery) and refinery process lines.
