Product details

Single Seated Control Valve

The valve body cavity of Parri's single seated control valve adopts an equal-section S-shaped flow channel design to minimize the flow resistance coefficient and effectively improve the flow capacity; the design of the guide vane is increased in the inner cavity, eliminating the possibility of the fluid medium forming a vortex in the inner cavity, based on The modular design concept, according to different working conditions, uses different combinations of trims to meet the process requirements of various common or harsh fluids.
