● The length of the structure is short series, the valve is light in weight, and the pipe support frame can be saved.
● The valve in the process of opening and closing the gate can scrape off the attached medium by itself, which is conducive to sealing.
● Knife gate is conducive to cutting off the medium, slagging, valve operation unblocked.
● Valve adopts clamp connection. Wedge limit provides sealing force and reliable sealing.
● Wear-resistant bushings of different materials can be provided according to requirements to extend the service life of the valve.
● Drive device (electric, gearbox, pneumatic, hydraulic) can be optional.

Side Entry Cryogenic Trunnion Mounted Ball Valve and extended valve cap ball valves will bring you huge profits in the field of low-temperature LNG services. Use temperature range-196°C~+150°C, with an extended valve cover design.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
The valve body is made of high-strength alloy steel or stainless steel, and is equipped with a precisely processed swing-type valve disc structure, enabling automatic control of the unidirectional flow of the medium. The optimized fluid dynamics design effectively reduces water hammer impact. The surface of the valve disc is clad with hard alloy to ensure reliable sealing under high-pressure and high-speed conditions. It is suitable for pipeline systems in industries such as petroleum, chemical engineering, and power.
