Pilot-operated check valve MDPC-08-P series

Product catalog summary

Technical Specifications

Operating Pressure: 207 BAR
Flow: 19 L/min
Internal Leakage: Maximum of 5 drops/min at operating pressure
Temperature Range: -40°C to +120°C (-40°F to +250°F)
Cavity: 08-3
Fluids: Mineral-based fluids with viscosities of 7.4 to 420 cSt

Product Features

Hardened, precision ground parts for durability
Industry common cavity
Compact size
Low leakage design

Operation

The valve allows flow from port ② to ③ while normally blocking flow from ③ to ②. Flow from ③ to ② is permitted when sufficient pressure is applied at port ①. The cartridge has a 3:1 pilot ratio, requiring at least one-third of the load pressure at ③ to open the valve.

Performance Curve

The document includes a performance curve illustrating the pressure drop versus flow rate, indicating the valve's efficiency under different conditions.

Installation Dimensions

Details on installation dimensions and torque specifications are provided, with a maximum torque of 27.1 Nm.

Order Type

Cracking Pressure: Options include 25 psi (1.7 bar), 50 psi (3.4 bar), and 100 psi (6.9 bar)
Seal-Kits: Buna N or Viton
Body Material: 6061-T6 aluminum (207 Bar) or steel (350 Bar)
Body Porting: Options include SAE 6T, SAE 8T, G3/8, NPT3/8, with other porting available

Application Areas

Transmission, engine, and powertrain control
Building and road construction equipment
Agricultural and garden machinery
Forestry and resource management equipment
Waste disposal equipment
Other professional mobile and industrial applications
