Pressure Control Valve

Their high performance results from the use of balanced and cage guided spools. pressure control valves are particularly well suited for heavy loads and any other application under the most demanding service conditions. Thanks to their simple construction, the wide range of internal parts types and the materials available, these high pressure regulating valve are suitable for a wide range of applications, including sour service with high temperature and corrosive fluids, and stringent low noise requirements.

Performance advantages

Modular design concept, combining the American and Japanese schools of high-precision control and the German school of modular concept.

The inner cavity of the valve body is S-shaped distribution, smooth and without dead ends; the valve body has internal guide wings, which can reduce the mutual force of the medium inside the valve body and reduce the occurrence of cavitation.

The use of sleeve guidance, large guide diameter, smooth guidance, with good dynamic stability.

The valve seat adopts floating design, while the sealing surface adopts tapered form to ensure good alignment of the sealing sub.

Sleeve window control flow characteristics, flow characteristics control accurately.

the structure of the inner part is balanced, allowing a large differential pressure, small operating force and large flow capacity.

Equivalent percentage, linear and quick-open flow characteristics are available.

Leakage level to meet in line with GB / T 17213.4-2005 / IEC 60534-4: 1999 Ⅳ level.

and pipeline connections are available in RF, RJ and other flange types and SW, BW welded types.      

Flange distance meets GB/T 17213.3-2005 / IEC 60534-3-1:2000; or ISA S75.03-1992 standard.

Key features and benefits of Pressure Control Valves

There are no practical constraints on the capacity for high pressure drops. The stability of the plug is enhanced due to an increased guide area. A broad spectrum of capacities can be achieved with a variety of reduced-capacity valve internals. Exceptional noise reduction is attained through low-noise single-stage valve internals designed for gas and steam applications. Enhanced protection against cavitation is provided for liquid services. Additionally, multi-stage valve internals are available to manage cavitation effectively. The balanced design of the plug minimizes thrust and reduces the size of the actuator. Furthermore, the pilot plug design ensures tight shutoff up to Class V in high-temperature environments.
