The Polyhydron PCM 06-06 is a pressure control module designed specifically for Hi-Low hydraulic systems. It functions by controlling double pumps—unloading the low-pressure (high-flow) pump to the tank when a set pressure is reached, while the high-pressure (low-flow) pump remains active to maintain system pressure.
The Polyhydron Pressure Control Module (PCM 20) is a manifold-based hydraulic unit specifically designed to control double pumps in a “Hi-Low” system. Its primary job is to efficiently manage high flow at low pressure and low flow at high pressure, which helps save energy and reduce heat in industrial machinery.
The Polyhydron PCM 20-16 is a pressure control module specifically designed for Hi-Low hydraulic systems that use double pumps. Its primary function is to manage the flow and pressure from two separate pumps to optimize efficiency—typically unloading a high-flow, low-pressure pump while a low-flow, high-pressure pump maintains system force.
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.
Polyhydron Counter Balance Valves (CB series) are direct-acting, seat-type valves used in hydraulic systems to control the descent of overrunning or gravity-induced loads. They prevent runaway loads and ensure smooth movement by creating backpressure in the return line.
The Polyhydron Counter Balance Valve (CB Design Series 30)Â is a seat-type valve designed for load-holding and safety in hydraulic systems. Its primary role is to provide a leak-free closure to hold a load in place and controlled flow for lowering it, preventing uncontrolled runaway movements.
The Polyhydron DPM is a direct-operated, spool-type pressure-reducing valve designed to lower a high primary pressure to a stable, lower secondary pressure. It is commonly used in hydraulic systems to protect components or maintain specific branch pressures.Â
The Polyhydron DPR is a direct-acting, poppet-type pressure relief valve designed for hydraulic systems. It functions by automatically opening a flow path from the inlet (port P) to the tank (port T) when the system pressure exceeds a pre-set limit, thereby protecting equipment from over-pressurization.Â
The Polyhydron DPS 06 is a direct-operated, spool-type pressure sequence valve designed to control the order of operations within a hydraulic circuit. It remains normally closed, sensing upstream pressure, and only opens to allow flow to a secondary actuator once a preset pressure level is reached.
The Polyhydron 2CB06T03 is a Dual Counterbalance Valve (often referred to as a “Duel” Counter Balance Valve in some regional catalogs). These are seat-type valves designed for hydraulic systems with overriding or suspended loads to prevent losing control of the load.
The Polyhydron MPPM 06Â is a pilot-operated, modular (stackable) pressure-reducing valve designed for vertical stacking assemblies. It is primarily used to maintain a constant, lower pressure in a sub-circuit of a hydraulic system, regardless of pressure fluctuations in the main circuit.
The Polyhydron MPPR 06 is a pilot-operated pressure relief valve designed with a modular (stackable) construction. It isprimarily used in vertical stacking hydraulic assemblies, allowing you to build complex hydraulic circuits without external piping.Â
The Polyhydron PPM series refers to their line of Pilot Operated Pressure Reducing Valves, which are used in hydraulic systems to provide a stable, reduced pressure at an outlet port.
The Polyhydron PPRU is a pilot-operated, two-stage poppet-type Pressure Relief cum Unloading Valve. It is specifically designed to manage systems with two pumps (High-Low systems) by unloading a low-pressure pump at a pre-determined pressure while maintaining high-pressure relief for the main system.Â
Polyhydron’s PPR series of Pilot Operated Pressure Relief Valves are two-stage poppet-type valves designed to protect hydraulic systems from over-pressurization. They are specifically valued for their high flow handling capacity, low pressure override, and versatility in mounting.
The Polyhydron PPR 06K is a pilot-operated, spool-type pressure relief valve designed in a cartridge format for high-performance hydraulic systems. It is known for its low pressure override due to a large flow area, ensuring system stability even during flow fluctuations
