Nachi pressure control valve

Nachi relief valve

  • Balanced piston relief valve
  • Optimum pressure control for hydraulic circuit allows operation as a safety valve.
  • A vent port enables remote control of pressure and use of an unloading circuit.

Nachi RI Series Relief Valve

  • High pressure capacity balanced piston relief valve
  • Optimum pressure control for hydraulic circuit allows operation as a safety valve
  • A vent port enables remote control of pressure and use of an unloading circuit.
  • ISO standard mounting service

Nachi Remote Control Relief Valve

  • Connecting a relief valve or reducing valve to the vent port of a balanced piston type pressure control valve provides simple remote control of pressure.
  • RCD type can also be used as a direct type relief valve.

Nachi SOLENOID CONTROLLED RELIEF VALVE

  • This valve adds a wet type solenoid valve to a balanced type piston type relief valve to form a hydraulic device unload circuit.
  • The shockless type has an internal structure that prevents shock generated during unloading. This valve can also be used in a pressure relief circuit, and has a maximum adjustment time of three seconds. See the pressure relief circuit example.
  • A two-pressure control circuit can be configured by adding a relief modular valve. Contact your agent for more information.

Nachi PRESSURE REDUCING (AND CHECK)VALVE

  • This valve is used when part of the circuit uses pressure that is lower than the main circuit.
  • Even when pressure changes in the primary main circuit, the reduced secondary pressure is adjusted automatically and maintained at a constant level.
  • Connecting a remote control valve to the vent port allows remote control of adjustment pressure.
  • The mounting surface of the gasket conforms to the ISO standards shown in the table below.

Nachi BALANCING VALVE (PRESSURE REDUCING AND RELIEF VALVE)

  • 2-in-1 operation allows a simpler circuit configuration. Combination valve that provides both pressure reducing and counter balance functions.
  • Pressure adjustment using a single screw (bolt).
  • Compact and lightweight valve that can be mounted using the same methods as a 01, 03 size solenoid valve.

Nachi PRESSURE CONTROL (AND CHECK)VALVE

  • This circuit control valve works as a sequence valve, unloading valve, and counter balance valve.
  • Maximum operating pressure is 21MPa {214kgf/cm2}.
  • Though a direct type valve, there is little pressure override.
  • The mounting surface of the gasket conforms to the ISO standards shown in the table below.
