  1. The pressure balanced design of the valve allows the reduced pressure to be kept constant without being influenced by the inlet pressure.
  2. The simple design makes the valve easy to disassemble for maintenance.
  3. Wide range of applications due to high working pressure.
  4. The large diaphragm area provides greater control accuracy for high set pressures.

*1. For use with other fluids, the valve manufacturer should be consulted.

* 2 The cable (Ø8, length 2 m) and the connection for the external impulse pipe must be ordered separately.

* 3. Variants available with fluoroelastomer components. <

[Precautionary measures]

  1. Connect the external impulse line to the tap on the pipeline.
  2. The needle valve of the pressure reducing valve should not be adjusted.
  3. The diameter of the external impulse tube for measuring pressure should be capable of a fluid flow velocity of 5-15 m / s.
  4. Pressure values for crimping or checking the tightness of the pipeline are shown in the table to the right.

* If more pressure is applied, the internal parts of the valve may be damaged.

Example Selection of the nominal size of the pressure reducing valve: inlet pressure (P1) —10 kPa, outlet pressure (P2) —3 kPa, flow rate 15 m3 / h (standard conditions). First you need to find the intersection point (a) of the inlet pressure graph (P1) for 10 kPa with the outlet pressure graph (P2) for 3 kPa. From this point a line should be drawn down to the intersection (b) with a flow characteristic of 15 m3 / h (standard conditions). Since the intersection point (b) lies between the 20A and 25A sizes, the larger of the two, 25A, must be selected. * The safety factor should be taken equal to 80-90%.
