The MCV116 is a torque‑motor actuated pressure control pilot valve that provides proportional hydraulic output from a DC input for electro‑hydraulic systems.
The MCV116 Pressure Control Pilot (PCP) Valve is a low‑cost, stand‑alone, closed‑loop valve used in electro‑hydraulic systems such as construction, farming, material handling, marine, mining and industrial equipment. It converts a DC control current into a proportional hydraulic differential pressure via a torque‑motor and double‑nozzle flapper mechanism.
The valve includes optional environmental connectors, intrinsic safety features, and can operate in both open‑loop and closed‑loop configurations. Detailed specifications cover scale factor, coil resistance, saturation current, temperature and pressure limits, as well as environmental data for shock, vibration and humidity. Wiring diagrams and connector options are provided for various installation scenarios.
| Scale Factor (Type 1) | 0.165 ± 0.014 bar/mA |
|---|---|
| Coil Resistance (Type 1) | 23 Ω |
| Saturation Current (Type 1) | 250 mA |
| Minimum Pressure | ±20.7 bar |
| Output Range (Delta psi) | ±300 psi |
| Ambient Operating Temperature | -40 °C to 93 °C |
| Weight | 0.73 kg |
| Hydraulic Operating Supply Pressure | 10.3 – 68.9 bar (150 – 1000 psi) |
The PCP accepts a DC current and produces a proportional hydraulic differential pressure.
Remove the adjustment screw and turn it with a 3/32‑inch hex key to set the null.
The valve can operate up to 93 °C (200 °F).
The coil resistance for Type 1 is 23 Ω (32 Ω in parentheses).
