Gate Valve Product Introduction

As a professional valve manufacturer with years of experience, Henan Hengye Valve Co., Ltd. is committed to providing high-quality, reliable slide valves for global industrial customers. Our slide valves are precision-manufactured to meet international standards, widely used in petroleum, chemical, power, water treatment and other industries, delivering stable performance and long service life for your pipeline systems.

Our slide valve is a kind of cut-off valve with gate plate moving vertically along the center line of the channel, which is mainly used for fully opening and closing the pipeline to cut off the medium, and is not suitable for flow regulation and throttling. With the design concept of "simple structure, reliable sealing and low energy consumption", the product effectively solves the pain points of easy leakage, large flow resistance and short service life of traditional slide valves, and is highly recognized by overseas customers.

In terms of material selection, we adopt high-quality cast steel, stainless steel and alloy steel, which have excellent high temperature resistance, pressure resistance and corrosion resistance, and can adapt to different harsh working conditions. The gate plate is divided into wedge type and parallel type, among which the wedge type gate plate adopts elastic design, which can make up for the deviation in processing and improve the sealing performance, while the parallel type gate plate is suitable for low-pressure and large-diameter pipelines, with more flexible application scenarios.

The product has obvious performance advantages: first, the internal medium channel is straight, the fluid resistance is small when fully open, the pressure loss is minimized, and the energy consumption of the pipeline system is effectively reduced; second, the opening and closing torque is small, the operation is labor-saving, and the trapezoidal thread design of the valve stem can convert the rotational motion into linear motion, ensuring smooth lifting of the gate plate; third, the medium flow direction is not limited, which is suitable for pipelines where the medium flow direction may change, and the installation is more convenient; fourth, the sealing performance is excellent, adopting forced sealing and self-sealing dual design, which can achieve zero leakage and ensure the safety of the pipeline system.
