Hydraulic Solenoid Valve for Sale​ Products Wholesale - ChangJia

Product Overview

- Product overview

Product Features

- Hydraulic solenoid valve series (ZDC...) supplied wholesale by CHONGQING CHANGJIA INTERNATIONAL TRADING CO., LTD. These are direct‑operated meter‑in pressure compensators available in 2‑way ("P") and 3‑way ("P T", NS10‑25) designs and include an integrated shuttle valve. They are intended for load compensation in channel P and for stable meter‑in flow control when paired with proportional directional valves.

Product Advantages

- Load compensation from port P to A or P to B with built‑in shuttle valve.

Application Scenarios

- Available in 2‑way and 3‑way versions (NS10‑25 for 3‑way).

- Direct‑operated control spool with compression spring and spring washer; cover incorporates the shuttle valve.

- Automatic pressure differential regulation: spring holds spool open while Δp < 1.0 MPa; spool shifts to restore Δp when it exceeds 1.0 MPa.

- Designed to work together with proportional directional valves for precise flow control.

- Product value

- Provides stable, automatic meter‑in pressure compensation to protect hydraulic circuits and ensure consistent actuator speed under varying loads.

- Improves system control accuracy when integrated with proportional valves, enabling finer flow metering and repeatable performance.

- Supports energy‑conscious hydraulic designs by maintaining efficient operation and helping reduce waste from pressure/flow fluctuations.

- Product advantages

- Robust, simple mechanical construction (housing, control spool, spring, shuttle) for reliable long‑term operation.

- Versatile 2‑way and 3‑way options cover common hydraulic circuit needs.

- Backed by ChangJia’s R&D, quality controls, advanced production equipment, and experienced technical team—enabling customization and consistent manufacturing quality.

- Company commitment to customer service, customization, and environmentally aware production adds commercial and operational confidence.

- Application scenarios

- Meter‑in pressure compensation in mobile or industrial hydraulic systems where load compensation is required (e.g., cylinders or motors subject to varying loads).

- Paired with proportional directional valves for precise flow control in machine tools, presses, material handling, and automation equipment.

- Suitable for OEM supply and bulk procurement for hydraulic system integrators, maintenance shops, and manufacturers needing customizable hydraulic components.
