Y42X stainless steel flange pressure reducing valve

Y42X stainless steel water pressure reducing valve is a pressure regulating valve with a spring directly acting film pressure reducing valve. This stainless steel pressure reducing valve is improved by Y416X spring diaphragm pressure reducing. The liquid pressure reducing valve is a valve that automatically maintains a stable outlet pressure by adjusting the inlet pressure to a certain required outlet pressure and relying on the energy of the medium itself. The working principle of the pressure reducing valve can be understood as the inlet pressure + outlet pressure = spring force. The pressure at the outlet is controlled by controlling the opening degree of the orifice in the pressure reducing valve. The smaller the opening degree, the more the liquid resistance of the liquid passing through the orifice is. The smaller, the smaller the pressure loss, the larger the outlet pressure, otherwise the smaller the outlet pressure to achieve the purpose of decompression.

Y42X stainless steel flange pressure reducing valve adjustment method

The valve core of the pressure reducing valve is usually closed when leaving the factory. First, set the required outlet pressure, remove the protective cap of the adjusting screw, loosen the fixing nut, and rotate the adjusting screw downward. The adjusting spring is compressed and exerts a force on the spring. Then, the spool opens, and the medium begins to flow through the spool from the valve inlet to the outlet. At this point the pressure at the outlet began to rise. Turn the adjusting screw downwards, and the pressure at the outlet of the pressure reducing valve rises. Turn the adjusting screw upwards and the pressure at the outlet of the pressure reducing valve decreases until it closes. Adjust the required outlet pressure according to the pointer of the pressure gauge behind the valve.
When the valve outlet pressure rises, the medium passes through the internal pressure feedback hole, and the force acting under the diaphragm increases, pushing the diaphragm upward, causing the valve core to close, the medium flow rate increasing, and the pressure drop increasing, which makes the pressure of the pressure reducing valve decline. Until it returns to the set pressure value.
When the outlet pressure drops, the force acting below the diaphragm decreases, and the valve core tends to open under the action of the adjusting spring, the medium flow rate decreases, the pressure drop decreases, and the pressure at the outlet of the pressure reducing valve increases. Until equilibrium.
