The basic properties and technical parameter of reducing valves
Valmax Valve Co.,Ltd.
(1) voltage range: it refers to the valve output pressure P2 of the adjustable range, meet the requirements in this range accuracy. The major areas of voltage regulator and the stiffness of the spring.
(2) the pressure characteristics: it refers to the flow g as the set value, the pressure fluctuations caused by the input output characteristics of pressure fluctuations. Smaller fluctuations in the output pressure, the better the characteristics of pressure reducing valve. Output pressure must be less than the input pressure - basically do not value it with the input pressure change.
(3) the flow characteristics: it refers to the input pressure - from time to time, holding the output pressure of the output flow and change of G. G when the flow changes, the output pressure changes as small as possible. Generally the lower the output pressure, which changes with fluctuations in the output flow smaller.
Temperature and pressure reducing valve technical parameters:
1, the nominal pressure: 1.0MPa, 1.6MPa, 2.5MPa
2, shell test pressure: P=1.5PN
The 3 seal test pressure: P=1.1PN
4, the outlet pressure regulating valve: PN1.0MPa 0.09~0.8MPa
PN1.6MPa control valve 0.10~1.2MPa
PN2.5MPa control valve 0.15~1.6MPa
5, suitable medium: water
