This 4WRPEH series hydraulic proportional directional valve is a direct operated proportional valve equipped with integrated electronics and spool position feedback. It adjusts hydraulic fluid flow and flow direction proportionally according to analog input signals to realize closed-loop control of speed, position and force in hydraulic circuits.
The valve adopts precision matched spool and sleeve structure. It delivers stable pressure performance, low hysteresis and good repeatability during continuous operation. The optimized internal structure reduces energy loss and suppresses noise level under normal working conditions.
The series covers multiple specifications with different rated flow options. It supports standard analog control signals and conforms to international mounting standards, which makes it compatible with most high-precision hydraulic control systems across various industrial sectors.

FEATURES
It realizes continuous proportional adjustment of flow and direction via electrical control signals, supporting flexible closed-loop control of hydraulic actuators.
The robust valve body structure can sustain high working pressure and keep stable control performance under heavy load hydraulic conditions.
Low hysteresis design ensures high control repeatability, and the internal structure reduces vibration for steady running status.
Precision matched internal components reduce wear rate. The integrated amplifier structure simplifies daily inspection and maintenance work.
It follows standard installation interface and common industrial control signals, which can be matched with most automatic hydraulic control systems.
APPLICATIONS
Absolutely. We provide OEM/ODM services and can manufacture according to your samples or technical drawings.
For in-stock items, we can ship within 3 days. For custom or non-stock items, delivery usually takes 7–15 days. We’ll confirm exact timing based on current inventory.
Yes, but it’s flexible. Spare parts often have an MOQ of 1 piece, while complete pumps or motors vary by model—please inquire for details.
We are a hybrid—both a manufacturer and a trading company. We produce our own products and also source specific components to offer complete solutions.
We follow strict quality control protocols. All parts undergo CNC machining and heat treatment, and each is 100% tested before delivery to guarantee precision and reliability.
We accept T/T, L/C, Western Union, Alibaba Trade Assurance, and VISA. For new customers, we usually require full prepayment or a 30% deposit with the balance due before shipment.
We offer flexible shipping via express carriers (DHL, FedEx, UPS) and sea freight (CIF/FOB). We can also deliver to your designated freight forwarder in China.
All products come with a 1-year warranty, provided they are installed and operated under normal conditions.
