Pressure Control Modules – PCM 30-16

The Polyhydron PCM 30-16 is a hydraulic Pressure Control Module (PCM) specifically designed to manage double-pump high-low systems. Its primary job is to automatically unload the low-pressure pump when the system reaches a set pressure, allowing the high-pressure pump to continue the work efficiently.

About this item

The Polyhydron Pressure Control Modules – PCM 30-16 is designed to control double pumps in a Hi-Low hydraulic system for efficient pressure management. It automatically unloads the low-pressure pump when system pressure exceeds the set value on the unloader valve. When the system pressure reaches the relief valve setting, the high-pressure pump is relieved to protect the system. An optional solenoid-operated unloading feature is available for enhanced control and operational flexibility.

Feature Details
High Pressure Flow Up to 100 L/min
Low Pressure Flow Up to 400 L/min
Max Pressure (High) 315 Bar (for high-pressure relief)
Max Pressure (Low) 100 Bar (for unloading)
Construction Two-stage poppet type for both high-pressure relief and low-pressure unloading
Hydraulic Medium Mineral oil (Viscosity: 10 cSt to 380 cSt)
Weight Approximately 1.75 kg
Common Application
This module is typically found in industrial machinery where high speed is needed at low pressure, followed by high force at low speed, such as:
    • Hydraulic Presses and Lifts
    • Power Packs
    • Industrial Machinery and construction equipment
