Products Hydraulic Flow Valve Supplier in China​ Factory

Product Overview

- A manual 3‑way pressure gauge isolator valve (type AF 6) supplied by Chongqing Changjia International Trading Co., Ltd. Designed to permit intermittent checking of system pressure by connecting or isolating a pressure gauge from the pressure line. Max. operating pressure up to 31.5 MPa; compatible gauge indicating ranges up to 6.3 / 10 / 16 / 25 / 40 (choose a gauge ~30% above system max).

Product Features

- 3‑way longitudinal spool design for simple P → gauge / gauge → T switching.

- Manual push‑button actuation with a rotatable detent to lock the spool in the switched position.

- Spring return mechanism automatically unloads the gauge when released.

- Gauge may be mounted directly into the valve housing or fitted separately.

- Compact, robust construction suitable for high‑pressure hydraulic systems.

Product Value

- Protects pressure gauges from continuous system exposure, extending gauge life and reducing maintenance.

- Enables safe, controlled pressure checks without shutting down or depressurizing the whole system.

- Simple, reliable operation minimizes operator training and reduces inspection time.

- Meets international quality standards, supporting consistent performance and reliability.

Product Advantages

- High pressure capability (to 31.5 MPa) for demanding hydraulic applications.

- Lockable actuation for stable hands‑free measurements when needed.

- Automatic unloading via spring reduces risk of gauge overload and improves safety.

- Manufactured under a quality management system and refined by technical improvements, ensuring market‑compliant performance and widespread acceptance.

- Flexible mounting options (direct or remote gauge installation).

Application Scenarios

- Industrial hydraulic systems (presses, injection molding, machine tools).

- Mobile hydraulic equipment (construction, agricultural and mining machinery).

- Test benches, commissioning and maintenance stations for pressure checks and diagnostics.

- Petrochemical, power generation and process plants where periodic gauge isolation is required.

- Any hydraulic system requiring reliable, compact gauge isolation and protection (consult supplier for uses outside listed parameters).
