High Quality Manual Directional Control Valve​ Company

Product Overview

- A high-quality manual directional control valve series (P50) supplied by CHONGQING CHANGJIA INTERNATIONAL TRADING CO., LTD., designed as a core component for hydraulic systems.

- Monoblock construction available in 1–7 sections; standard nominal flow 50 L/min (13.2 GPM) and maximum working pressure 250 bar (3626 PSI).

- Broad control and actuation options including manual, hydraulic, pneumatic, electro‑pneumatic, electro‑hydraulic, solenoid, joystick and cable configurations.

- Engineered for a wide working viscosity (15–75 mm²/s) and ambient temperatures from −40° to 80°C.

Product Features

- Monoblock P50 design provides compact, modular assemblies up to seven levers/sections.

- Multiple actuation methods allow flexible integration into diverse systems and control architectures.

- Robust operating envelopes: 50 L/min flow capacity, 250 bar pressure rating, wide viscosity and temperature ranges.

- Produced with non-traditional, higher-grade raw materials and subjected to strict quality inspections throughout manufacture.

- Technical documentation and section drawings (e.g., 2P50) available on request for system design and installation.

Product Value

- Ensures reliable directional control of hydraulic fluid to optimize performance and safety of hydraulic circuits.

- Modular, multi-section design reduces inventory and simplifies system expansion or customization.

- Wide control method compatibility enables reuse across different machines and control strategies, lowering total system cost.

- Durable materials and comprehensive quality control lower downtime and maintenance costs over the product life cycle.

- Manufacturer support and available drawings accelerate specification, ordering and installation.

Product Advantages

- Superior material selection and continuous quality checks aimed at defect-free, high-performance valves.

- Flexible configuration (1–7 sections) and extensive control options for fast adaptation to customer needs.

- Clear technical ratings (flow, pressure, viscosity, temperature) simplify system sizing and reduce integration risk.

- Experienced production, sales and service teams provide professional support and faster order handling.

- Established brand reputation and focus on product development and innovation within the hydraulic market.

Application Scenarios

- Industrial hydraulic power units and factory automation systems.

- Mobile and off‑road equipment: construction machinery, agricultural machinery, material handlers.

- Marine and offshore hydraulic installations.
