Directional Valve by ChangJia

Product Overview

- The LKF114 Directional Valve from ChangJia is a pressure‑compensated, variable flow control valve (flow control valve) designed to maintain a set flow regardless of pressure changes. Key specs: oil port NPT3/4 or G3/4, flow range 0–114 L/min, maximum working pressure 0–21 MPa. Made from high‑quality raw materials and produced under a stringent quality assurance system.

Product Features

- Full‑range, pressure‑compensated variable flow control design.

- Flow adjusted by rotating the valve spool to change the orifice area.

- Flow regulation is independent of other port pressure channels (pressure‑independent flow).

- Two configurations available: with or without an adjustable spring safety (relief) valve.

- Compact standard ports (NPT3/4 or G3/4) for straightforward integration.

Product Value

- Delivers stable, accurate flow control under varying load or system pressure, improving process consistency and machine performance.

- Protects downstream components by preventing over‑flow or pressure spikes when equipped with the adjustable safety valve.

- Reduces the need for frequent tuning and simplifies hydraulic circuit design, lowering operating costs and downtime.

- Backed by ChangJia’s quality management and after‑sales support for reliable long‑term operation.

Product Advantages

- Pressure compensation ensures set flow is maintained despite pressure fluctuations.

- Wide flow capacity up to 114 L/min and high working pressure rating (up to 21 MPa) for demanding applications.

- Option for integrated adjustable safety relief enhances system protection and flexibility.

- Standardized porting (NPT/G 3/4) eases installation and retrofitting.

- Manufactured from high‑quality materials under strict QA for consistent performance and odor‑free use.

Application Scenarios

- Industrial hydraulic systems requiring constant flow to actuators or hydraulic circuits (machine tools, presses).

- Mobile and construction equipment where load pressure varies but flow must be stable (excavators, cranes).

- Injection molding and plastics machinery for consistent material dosing.

- Test benches, hydraulic service rigs, and laboratory setups needing precise flow control.

- Agricultural, mining, and marine hydraulic systems where robust, protected flow control is required.
