Wholesale Directional Valves Factory Directional Valves Wholesale - ChangJia

Product Overview

- The ChangJia LKF60 series wholesale directional/flow control valve is a pressure‑compensated, variable flow control valve designed for accurate, stable hydraulic flow regulation. It is built from durable, eco‑friendly materials and manufactured under strict quality inspection procedures. Key technical data: model LKF60, oil port NPT1/2 or G1/2, flow range 0–60 L/min, working pressure up to 21 MPa. Two configurations are offered: with or without an adjustable spring safety (relief) valve.

Product Features

- Pressure‑compensated variable flow control (full range) for consistent flow regardless of load pressure fluctuations.

- Flow adjustment via rotary movement of the valve spool to vary the orifice area.

- Independent control that isolates the metered flow from other port pressure channels.

- Available safety option: adjustable spring safety (relief) valve for overpressure protection.

- Constructed from long‑life, environmentally friendly materials and produced under a strict material selection and quality inspection regime.

Product Value

- Provides precise, stable flow control to improve the performance and repeatability of hydraulic circuits.

- Enhances system safety and protection when equipped with the adjustable relief option.

- Durable, eco‑friendly construction reduces maintenance and environmental impact over the product lifetime.

- As a factory‑supplied model, it offers competitive pricing and reliable supply for OEMs and bulk buyers.

Product Advantages

- Rigorous raw material selection and strict quality control eliminate defects and ensure consistent performance.

- Full‑range pressure compensation maintains set flow even with upstream/downstream pressure changes.

- Two configuration options let users prioritize either cost or integrated safety protection.

- Manufacturer advantages: experienced producer with strategic location for efficient access to materials, skilled labor and lower production/shipping costs—translating to competitive pricing and dependable delivery.

Application Scenarios

- Hydraulic systems requiring accurate flow metering and load‑independent control (industrial presses, machine tools).

- Mobile hydraulics in construction, agriculture and material‑handling equipment.

- Power units and pump circuits where constant flow is needed despite pressure variations.

- Test benches, hydraulic emulation rigs, and process control equipment.

- Any application demanding durable, low‑maintenance flow control with optional overpressure protection.
