This combined set includes 4WRL25V370M-30/G24Z4 M pilot-operated proportional directional valve and 4WRPH6C3B24L-20=G24Z4/M=00 direct operated proportional directional valve. Both are equipped with proportional solenoid and spool position feedback system. Electric control signal drives spool displacement to continuously adjust flow rate and flow direction for hydraulic actuators.
The valves maintain high repeatability and low hysteresis under variable working loads. Precision matched spool and sleeve assembly reduces internal leakage, guarantees accurate flow regulation and suppresses hydraulic shock during frequent dynamic adjustment cycles.
This proportional valve family has multiple size and flow rating selections. It adopts closed-loop proportional electric control and can integrate into various high-performance hydraulic circuits. It serves as high-precision motion control components for stationary and mobile heavy-duty hydraulic equipment.

FEATURES
Built-in spool position feedback realizes closed-loop control, enabling continuous and stepless adjustment according to analog electric input signals.
Precision spool and sleeve machining minimizes internal leakage and maintains stable flow output under high working pressure.
Optimized spool profile shortens response time and reduces pressure shock and vibration during dynamic flow adjustment.
High-grade matching components and reliable sealing materials reduce abrasion and lower regular maintenance requirements.
Standard ISO subplate mounting pattern supports simple installation and replacement for various high-precision 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.
