PLVD Series Hydraulic Lift Valve | Hidroman
Hydraulic Lift and Platform Valve for Controlled Movement
Reliable lifting and controlled lowering are essential in hydraulic lift and platform systems. The Hidroman PLVD Series Hydraulic Lift Valve is designed to help control hydraulic oil flow, regulate lowering speed, and manage system pressure in compatible hydraulic applications.
The PLVD Series supports 12 V, 24 V, and 220 V coil options, providing flexibility for different electrical control requirements. Its integrated check valve, dual-speed adjustment function, dual solenoid poppet valves, and adjustable pressure relief valve support key hydraulic circuit functions.
Final valve selection must be based on the system's operating pressure, flow rate, electrical requirements, connection standard, and applicable safety requirements.
How Does the PLVD Series Hydraulic Lift Valve Work?
The PLVD Series controls hydraulic flow during lifting and lowering operations.
1. Lifting operation
Hydraulic oil supplied by the pump passes through the integrated check valve and flows toward the cylinder. The lifting cycle is stopped by the system's control arrangement when the required position is reached.
2. Controlled lowering
During lowering, the solenoid poppet valve opens to establish the return flow path. Hydraulic oil passes through the speed adjustment valve, allowing the lowering speed to be regulated.
3. Two-stage lowering speed adjustment
The dual-speed adjustment function and dual solenoid poppet valves allow the lowering speed to be adjusted in two stages. The appropriate settings depend on the hydraulic circuit design and application requirements.
4. Pressure relief
The adjustable pressure relief valve in the pump line helps protect the hydraulic circuit against excessive pressure by directing oil to the tank when the pressure exceeds the selected setting.

Applications for Hydraulic Lift Valves
Depending on system compatibility and engineering requirements, the PLVD Series may be considered for:
Hydraulic platforms
Hydraulic lifting and lowering mechanisms
Cranes
Excavators
Vehicle-mounted hydraulic equipment
Suitability for a particular lift or platform must be verified against the load requirements, cylinder specifications, operating pressure, flow rate, electrical controls, and applicable safety standards.
How to Select the Right Hydraulic Lift Valve
Choosing a hydraulic lift valve requires more than matching the port connection. Consider the following factors:
Operating pressure: Verify normal operating pressure and maximum system pressure.
Required flow rate: Match the valve to the pump flow and desired cylinder speed.
Coil voltage: Confirm whether the control system requires a 12 V, 24 V, or 220 V coil, including the correct AC/DC configuration.
Connection standard: Check whether BSP, NPT, or metric connections are required.
Seal material: Select suitable seals based on hydraulic fluid, temperature, and operating conditions.
Lowering and load-control requirements: Confirm that the valve functions are appropriate for the system's load-control and controlled-lowering design.
Hydraulic lifting systems must be engineered with suitable safety devices and correctly commissioned. Valve compatibility should be assessed as part of the complete hydraulic system.
Frequently Asked Questions
What does a hydraulic lift valve do?
A hydraulic lift valve controls hydraulic oil flow in a lifting system and helps manage lifting, lowering, and, where supported by the design, lowering speed.
What coil voltages are available for the PLVD Series?
The Hidroman product information lists 12 V, 24 V, and 220 V options. Confirm the coil's AC/DC configuration and electrical specifications before ordering.
Can the PLVD Series adjust lowering speed?
Yes. The product description specifies dual-speed adjustment and dual solenoid poppet valves for two-stage lowering speed control. Final adjustment depends on the hydraulic circuit.
What materials are used in the valve?
The valve body is aluminum. The standard sealing material is nitrile O-ring (NBR), with a Viton option available for special requirements.
Is the PLVD Series suitable for every hydraulic lift?
Not automatically. Verify pressure, flow, connections, coil configuration, load-control functions, and applicable safety requirements before selecting the valve.
