DOROT 31-10F

Diaphragm-actuated, 3-way Spring-loaded, Rate-of-Flow, Metal Pilot Valve

DOROT 31-10F, is a Diaphragm-actuated, 3-way Spring-loaded, Rate-of-Flow, Metal Pilot Valve, designed for control of flow-regulating hydraulic valves. The pilot valve operates as a selector between the common port and the two other ports.
Operation principle
The pilot will vent, pressurize or lock the hydraulic valve chamber, as a factor of the relation between the pressure differential across a supplementary orifice plate and the adjusted preset value.

Features & Benefits

Differential pressure regulating 3-way pilot valve
  • Enables precise control of flow rates by adjusting pressure differentials, to optimize system performance.
Fully vents control chamber to minimize pressure losses
  • Reduces energy waste through efficient venting, especially when pressure drops below preset value.
Pressure-balanced design
  • Maintains consistent performance even during large upstream pressure variations.
Superior sensitivity and repeatability
  • Enables highly accurate and consistent control of pressure settings; improving system stability.
Versatility for multiple control functions
  • Suitable for a variety of hydraulic control functions, such as flow rate control and pressure differential regulation.
Designed for high performance with orifice plate integration
  • Improves system adaptability by linking with orifice plates, for fine-tuned pressure control.
