Import Cartridge Valve 3 In 1 Multi-Function — Buy in wholesale FOB from Supplier in China

The Cartridge Valve 3 in 1 Multi-Function is an integrated hydraulic threaded cartridge valve that combines a check valve, a relief valve and an electromagnetic unloading valve in a single unit. It replaces three separate HydraForce valves, reducing component count and simplifying hydraulic circuit design. The valve housing features a connecting valve hole that links the oil cylinder working port, a hydraulic control port, an oil inlet port and an oil return port. Inside, a check‑valve spool controls on‑off flow between the inlet and working port, a control check‑valve spool manages unloading, and a relief‑valve spool provides overflow protection.

The body is typically forged carbon steel, while the internal spools are hardened stainless steel, delivering durability under cyclic loading. Standard NPT threads allow screw‑in installation compatible with common hydraulic manifolds. Typical operating pressure for similar cartridge valves is up to 25 MPa, and the valve can function from - 20 °C to 120 °C, covering most industrial temperature ranges. The integrated design also incorporates a damping hole with an unloading valve spool to modulate flow and reduce pressure spikes.

This valve is suited for hydraulic cylinders in mobile equipment, construction machinery and industrial presses where space and weight savings are critical. OEMs and system integrators often select it to achieve a compact cylinder architecture and lower overall system cost. Aak Industry can supply samples, as demonstrated by a previous delivery of ten units after a 50‑day prototype phase, and bulk orders can be arranged once the design is approved. Buyers should confirm exact MOQ, lead time and payment terms directly with the supplier, as these details are not published.

Aak Industry Co., Ltd is located in Yinzhou, Ningbo, Zhejiang Province, China, at No. 456 Taikang Middle Road. The supplier is listed with a harbour trust tier on the platform, but the response rate is recorded as 0.00 and no average response time is available, indicating that communication may require proactive outreach. The company’s address and registration details are publicly provided, allowing buyers to verify its legal existence and geographical base.

The company offers an integrated hydraulic threaded cartridge valve that merges three standard hydraulic functions into one compact unit. A recent case described a Spanish OEM that required a custom valve to replace three separate HydraForce components; Aak Industry engineered the solution, supplied ten samples after a 50‑day development period, and received positive feedback that led to a pending batch order. The listing does not disclose additional certifications or production capacity, so interested importers should request specific technical documentation and confirm any customization capabilities.
