Hydraulic Flow Valve by ChangJia

Product Overview

- Hydraulic Flow Valve by ChangJia is a pressure- and viscosity-dependent throttle product family designed for direct in-line mounting.

- Offered in two functional types: MG (bi-directional throttle) and MK (throttle check valve with one-way free flow).

- Manufactured and inspected by CHONGQING CHANGJIA INTERNATIONAL TRADING CO., LTD to meet industry standards, with controlled material selection and quality processes.

Product Features

- Suitable for direct in-line mounting for compact, straightforward installation.

- Pressure- and viscosity-dependent operation for predictable throttling behavior under typical working fluids/temperatures.

- Type MG: steplessly adjustable throttling in both flow directions via a rotating adjustable sleeve.

- Type MK: throttles in one direction and allows free, unthrottled flow in the opposite direction using a poppet/spring mechanism; annular clearance provides a self‑cleaning effect.

- Performance characterized by measured curves (example given at v = 41 mm²/s and t = 50°C).

Product Value

- Enables accurate flow regulation and speed control in hydraulic circuits, improving system performance and stability.

- Adjustable design allows fine-tuning on-site to match process requirements.

- Self-cleaning and check features reduce maintenance frequency and help protect downstream components.

- Backed by controlled manufacturing and inspection, offering reliable and consistent performance.

Product Advantages

- High build quality from strict design, material selection, and inspection systems—claims superior quality versus many industry alternatives.

- Flexible product range (MG and MK) covers both bi-directional throttling and combined throttle/check needs.

- Simple stepless adjustment and direct in-line mounting make installation and commissioning easier.

- Produced using modern techniques and international quality norms, with customer-oriented service and operational sustainability focus.

Application Scenarios

- General hydraulic systems requiring flow or speed control of actuators (cylinders, motors).

- Circuits needing one-way bypass or load-holding with controlled return flow (e.g., MK used where free flow in one direction is required).

- Mobile machinery (construction, agriculture), industrial manufacturing equipment, material handling, and other oil-hydraulic installations.

- Any in-line hydraulic piping where reliable, adjustable throttling and low-maintenance operation are desired.
