Yg43h Pneumatic Regulator, High Sensitivity Steam Pressure Reducing Valve

YG43H Downstream-pressure controller- High sensitivity steam pressure reducing valve
High sensitivity steam pressure reducing valve is a control valve which work with the valve inner open-close part's opening size to control the medium flow and reduce the medium pressure. At the same time with downstream pressure of the valve to adjust the opening, keep the valve downstream pressure within a certain range. When the inlet pressure keep changing, the outlet pressure sustained within the set range. So it can protect the downstream living and producing products safety.
2. High sensitivity steam pressure reducing valve is a necessary accessories of pneumatic control valve. Its main function is to reduce and sustain the air source pressure to a fixed value. So that the pneumatic pressure control valve can obtain a stable gas source power.
According to the structural form, this pressure reducing valve can be divided into diaphragm type, diaphragm spring, piston, lever type and bellows type; According to the seat number, the pressure reducing valve have single-seat and two-seater type; According to the position of the valve disc, the pressure reducing valve can be divided into positive acting type and reverse acting type.

High sensitivity steam pressure reducing valve is controlled with the downstream pressure, is downstream-pressure controller. When the valve pressure sensor detected the valve pressure increased, the pressure reducing valve opening decreased; When detected the relief valve downstream pressure decreases, and increase pressure reducing valve opening, in order to meet the control requirements.

High sensitivity steam pressure relief (reducing) valve------this valve's Pressure reducing ratio must be higher than the system to a certain extent value; Even at the maximum or minimum flow condition, it should also be able to respond to positive action and reverse acting control signal. These valves should be working at a selecting control range, mean 20% to 80% of the maximum flow. Normally is equal proportion or with features of proportion. These types of valves are with the best flow characteristics and flow range of proportional control valve demands itself.

Tianjin U-ideal Instrument Co. Have Many different kinds of pressure reducing valve, such as: The piloted piston type pressure reducing valve, diaphragm pressure reducing valve, bellows type pressure reducing valve, proportional pressure reducing valve, self-reliance type pressure reducing valve, direct acting piston type pressure reducing valve, back pressure regulator, etc. They apply respectively to different working medium.
