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.

The self-regulating control valve is an energy-saving control device that does not require external driving energy. It relies on the pressure or temperature of the medium being regulated as its power source, automatically adjusting according to set values based on changes in the medium. This valve integrates multiple functions of detection and control into one unit, forming an independent instrument control system. The self-operated control valve adopts a standard modular design. Our products are characterized by: standardization, serialization, and generalization. This achieves a high level of these three aspects. The components of the self-operated pressure regulator and differential pressure regulator are interchangeable. If the control conditions change, the spring & diaphragm components can be easily replaced. The accuracy of the self-operated control valve surpasses that of similar products, and it also offers high stability. Diversified product series: self-operated pressure regulator, self-operated micro-pressure regulator, self-operated temperature regulator, self-operated flow regulator, self-operated nitrogen-sealing valve, and self-operated (combined) regulator...
Our company has developed a variety of series of Angle control valves. They feature a compact valve body structure, low pressure drop loss, large flow rate, unobstructed flow channel with low resistance within the adjustable range, and high accuracy of the flow curve. It is particularly suitable for regulating high-viscosity fluids containing suspended solids and granular materials, which can prevent coking, adhesion, clogging and other phenomena, and is convenient for self-cleaning and cleaning. The control valve is equipped with the RSMF type multi-spring pneumatic diaphragm actuator, which features a simple and firm structure, large output force and long service life.
Compared with other valve products, High Temperature and High Pressure Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The high-temperature and high-pressure gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the sealing surface of the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
