Smart Systems Driven by Line Pressure

Hydraulic control valves are globe-style valves that perform opening, closing, and regulation operations using the water pressure already present in the pipes. Through a flexible diaphragm and mounted pilot mechanisms, they handle various tasks such as pressure reduction, pressure sustaining, flow control, and level control. With ductile iron bodies and corrosion-resistant epoxy coatings, they offer years of maintenance-free service in municipal infrastructure, agricultural irrigation, and industrial water systems. They provide full protection against mechanical damage by dampening water hammers.

Functional Diversity

  • Pressure Reducing: Lowers inlet pressure to a constant outlet pressure.
  • Pressure Sustaining: Prevents line pressure from falling below a set limit.
  • Solenoid Control: Enables remote on-off via electrical signals.

Technical Benefits

  • No external energy (electric, air) required for basic operations.
  • Precise pressure regulation via micro-pilot adjustments.
  • Leak-proof and stable closing even at very low pressures.
