Support OEM customization


Control & structure: Pneumatic-operated, single-section monoblock design reduces external leak points and simplifies installation for OEM integration.
Performance: Rated flow 40 L/min (10.5 US gpm) with max pressure 1 MPa (145 psi), suitable for pneumatic-driven directional switching in compact circuits.
Fluid & environment adaptability: Supports 12–400 mm²/s viscosity range and ambient temperatures from -40°C to +80°C, helping maintain consistent operation in cold storage, outdoor equipment, and variable-duty industrial environments.
Typical applications: Directional control for actuators and mechanisms on material handling and industrial vehicles (e.g., forklifts, stackers, aerial platforms), as well as selected construction/agricultural auxiliary functions where pneumatic control is preferred.
Supply capabilities: Factory direct manufacturing for global markets—OEM/ODM, private label, customization (ports, mounting, interfaces, labeling/packaging), wholesale, and distributor/agent cooperation.
