HTHP Slab Gate Valve has small fluid resistance, and the internal medium channel of the valve body is directly connected. The medium does not change its flow direction when the gate flows through the gate valve. The pressure self-tightening seal is adopted, and the two ends of the valve body branch pipe are usually welded. The torque required for opening and closing is small, the body structure is simple, the manufacturing process is better, the sealing performance is good, and the corrosion of the dense cover when the full opening is less. The scope of application is wide. The phenomenon of water hammer is not easy to produce due to the long closing time. The medium can flow to either side in any direction, easy to install.

Application range: High-temperature and high-pressure gate valve is generally used in the shape of the valve's shape without strict requirements, but the use conditions is relatively harsh. Such as high-temperature and high-pressure working medium. Such as the application of power industry, petroleum refining, petrochemical, and marine petroleum.

This product is a new type top entry combination ball valve,the seat can be installed and move around the body. Through the thread, the outer margin of the seat connected to the retainer ring. There is spring on the support cover, which installed on the valve body, and the retainer ring can compress spring.
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.
Special type control valves are customized valve products designed by our company for complex working conditions (such as high temperature, high pressure, strong corrosion, high precision, and low-temperature control, etc.). They possess the ability to precisely regulate flow and pressure, and can meet the stringent requirements in industrial processes.
