● 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.

The Rotary Ball Valve adopts advanced ball rotation sealing technology and is specially designed for harsh working conditions. It is suitable for the control of high-pressure, high-temperature and corrosive media in industries such as petroleum, chemical engineering, natural gas, and power. Its unique rotating valve seat structure effectively reduces friction and wear, ensuring more durable sealing performance and easier operation. The valve body is made of high-quality stainless steel, carbon steel or special alloy materials, and is precisely processed and hardened to ensure long-term stable operation. It supports various driving methods such as manual, pneumatic, and electric, meeting different automation requirements and is an ideal choice for industrial pipeline fluid control.
The “Double Block and Bleed Isolation Philosophy” requires two in-line isolation valves and a bleed valve, used to drain or vent trapped fluid between the two closure elements in order to safely isolate safely the downstream pipe. This feature can be achieved with one single valves c/w a bleed port between the obturators.
The Throttle Stop Valve is mainly composed of valve body, valve cover, valve flap, and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals to move it up and down along the valve stem axis to realize the full-opening, full-closed movements and regulating traffic functions. The force applied by the hand wheel can be obsessed with the valve seat to reach the sealing state; Location, change the cross-sectional area between the valve petals and the cover of the valve seat, and achieve the purpose of regulating media flow. At the same time, the throttle stop valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the life of the valve.
