Angled valve for applications that require the application of the right-angle connector
Can save a right angle bend and installation space. Flow path through the valve, suitable for high viscosity fluid control containing suspended solids and particles.angle seat valve
Another difference is angled valve through the valve only a single guide, therefore, can not be anti-loaded valve spool gas open or air to close the conversion of the mode of action can only be selected or reverse acting executive agencies to implement the conversion of the mode of action. Figure 2-6 is a configuration diagram of the angular valve. Angular valve fluid is generally from the bottom of the inflow and outflow from the side of the valve. Thus, the suspended solids or particles in the fluid is not easily deposited in the valve to avoid coking and plugging, having the self-purification capacity, ease of maintenance and cleaning, but scouring the spool. Side into the bottom of the flow of the erosion damage on the spool can be improved, but when the small opening, the flow off flows prone undercutting phenomenon, the undercut phenomenon is small when the degree of opening of the fluid flow · causing changes in the direction of the imbalance force, so that the spool oscillation instability. In order to reduce the imbalance of power and improve the erosion of the spool can be used icon with balance holes sleeve structure. The angled valve flow path resistance is small, therefore, can reduce the pressure drop across the valve, the energy-saving effect.pneumatic fitting
The high-pressure valve high pressure valves are suitable for high static pressure and high differential pressure applications. The high-pressure valve is usually used the angular single seat structure, foreign high-pressure valve integral forged structure.pneumatic accessory
