Product Introduction

LYV® High Pressure Resistant Gate Valve is specially designed to overcome the harshness of industrial pressure. We offer two main connection forms: Flange High Pressure Gate Valve and Sealed Welded Gate valve for High Pressure, to meet different installation and permanent sealing requirements. Its valve body is made of high-quality forged steel and has undergone precise processing and heat treatment to ensure structural integrity under continuous high pressure. Its 900LB-2500LB High Pressure Gate valve specifications can fully cover various complex working conditions from medium pressure to ultra-high pressure.Through the rigid gate plate and self-tightening sealing design, High Performance High Pressure Gate valve builds a solid and reliable barrier in the face of high pressure.

What's the typical application scenarios of High Pressure Resistant Gate valve？

●Oil and gas industry: oil and gas field wellhead equipment, high-pressure gathering and transportation pipelines, fracturing equipment and natural gas compression stations and other ultra-high pressure scenarios.

●Chemical engineering and coal chemical engineering: Inlet and outlet of high-pressure synthesis reactors (such as ammonia synthesis, methanol synthesis), high-pressure material conveying pipelines and urea plants.

●Power station system: boiler feed water system, main steam pipeline, high-temperature and high-pressure bypass and power station auxiliary system.

●High-pressure testing and experimental equipment: Various process test circuits, test benches and fluid control systems that need to withstand extreme pressure.

What's the working principle of High Pressure Resistant Gate Valve in high pressure environments?

Under high-pressure conditions, the gate of a high-pressure resistant gate valve acts like a sturdy wedge, driven by the valve stem to be vertically inserted between the two valve seats, achieving mechanical rigid shut-off. When the system pressure rises, the medium pressure will act on the valve seat from the back of the gate plate. This force will be converted into an additional clamping force that pushes the valve seat towards the sealing surface of the gate plate, forming a "pressure-assisted sealing" effect. For high-pressure sealed welded gate valves with welded connections, they are integrated with the pipeline, completely eliminating potential leakage points at the flange connection, minimizing the pressure-bearing boundary, and achieving the highest level of sealing integrity in principle. They are the ultimate solution for ultra-high pressure and high-risk medium pipelines.
