Throttle stop vent valve
The Throttle Stop Vent Valve is designed for safe venting, depressurization, and controlled flow release in high-pressure pipelines, boilers, and pressure vessels. Its precision throttling mechanism ensures smooth operation, reliable sealing, and minimal leakage. Suitable for gases, steam, and liquids, it enhances system safety, efficiency, and maintenance management.
Throttle stop vent valve
The Throttle Stop Vent Valve is engineered to regulate venting and pressure relief in industrial pipelines and vessels. The integrated throttle mechanism allows precise flow control, preventing sudden pressure surges and ensuring smooth operation.
Constructed from durable carbon steel, stainless steel, or alloy steel, it offers excellent corrosion resistance, high-temperature tolerance, and reliable sealing. The valve can be manually operated or fitted with pneumatic/electric actuators for automation. OEM customization enables adaptation of size, material, pressure rating, and connection type for specific industrial requirements.
Throttle Stop Vent Valves meet international industrial standards:
