Friction-Free Operation: The ball turns only after moving away from the seat, eliminating friction and reducing wear common in traditional ball, gate, and plug valves.
Injectable Packing: Allows for online maintenance by injecting packing into the stem through a port, effectively controlling emissions. This feature is applicable to all models with a sealed cover.
Single Seat Design: The rising stem ball valve's single static seat ensures zero downstream leakage and avoids the pressure build-up issues common with double-seated designs.
Extended Service Life: This valve can replace other valves prone to sealing failures, such as standard ball valves, gate valves, and plug valves, reducing failure rates and maintenance costs significantly.
Optimal Flow Characteristics: Both full-bore and reduced-bore valves maintain high Cv values when open, enhancing pump efficiency and minimizing corrosion issues.
Top Entry Design: Facilitates inline inspection and maintenance after decompressing the pipeline system, simplifying upkeep.
Dual Stem Guides: The stem moves smoothly up and down, and rotates along guide pins, ensuring stable control.
Self-Cleaning Feature: When the core is off the seat, the medium flows 360 degrees along the sealing surface, washing away impurities.
Low Torque Operation: The elimination of sealing friction makes the valve easy to turn, allowing the use of a small handwheel without the need for a gearbox, except in very large sizes.
Wear-Resistant Hard Sealed Surfaces: The core's sealing surfaces are overlayed with hard alloy and polished, maintaining seal integrity even under harsh conditions.
Mechanical Wedge Seal: The inclined surface at the bottom of the stem provides a mechanical wedge force, ensuring continuous tight contact between the core and the seat.

CHM703 High Pressure Control Valve is a high-precision fluid control device specially designed for harsh industrial environments. It is suitable for high-pressure pipeline systems in industries such as petroleum, chemical engineering, power, and metallurgy. This product uses high-quality materials and advanced manufacturing techniques to ensure stable operation even under extreme conditions such as high pressure, high temperature, and strong corrosion. Its compact structure and reliable sealing enable precise regulation of flow and pressure, meeting the strict requirements of complex industrial processes. The high-pressure regulating valve has excellent shock resistance and vibration resistance, and is suitable for frequent opening and closing and high-load operation environments. It is also easy to maintain, effectively reducing long-term usage costs, making it an ideal choice in the field of industrial fluid control.
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.
Self-Operated Micro-Pressure Regulator does not require additional driving energy and is a kind of energy-saving control device; it is a specialized product for current most popular nitrogen sealing system of storage tanks.
