High-Pressure Plate Ball Valve QJH YJZQ Series Plate Stop Valve J10B J20B J25B QJH10B 20B

Product Overview
The Series 5 high-pressure plate-type ball valves and globe valves are ideal basic control components designed specifically for hydraulic manifold systems (hydraulic power units, hydraulic valve groups). Abandoning traditional threaded connections, they directly connect to pre-machined valve blocks via the flat surface and sealing ring at the bottom of the valve body, secured with bolts. This design significantly saves installation space, simplifies pipeline layout, and enhances system neatness and reliability. Suitable for various high-pressure hydraulic equipment requiring frequent opening/closing or oil circuit isolation.

Detailed Product Features and Advantages

1. Plate-Type Connection, Core of Manifolding

• Space Saving: Directly mounted on the valve block surface, no additional pipe fittings or connecting pipelines required, resulting in an extremely compact system structure.
• Fewer Leakage Points: Reduces potential leakage risks at threaded connections, improving system sealing reliability.
• Easy Installation: Can be easily fixed with bolts, featuring simple installation and disassembly for high maintenance efficiency.
• Lower Flow Resistance: Optimized flow channel design enables smooth transition with the valve block oil port, minimizing pressure loss.

2. Clear Functions, Optional as Needed

• Ball Valves (e.g., QJH Series): Used as on/off valves, featuring simple operation (90° rotation) and minimal flow resistance. Suitable for occasions requiring quick, complete cut-off or connection of oil circuits.
• Globe Valves (e.g., J10B, J20B Series): Used as regulation and on/off valves, allowing precise flow adjustment via handwheel. Slow opening/closing effectively prevents hydraulic shock, suitable for occasions requiring throttling or fine control.

3. High-Pressure Resistance, Stable and Durable

• Valve body made of high-strength alloy steel or stainless steel, with excellent pressure-bearing capacity.
• Key sealing components adopt imported high-quality materials, featuring excellent oil resistance, aging resistance, and high/low temperature resistance for long service life.

4. Complete Models, Compatible and Interchangeable

This product series covers multiple domestic mainstream model standards (such as QJH, YJZQ, J10B/J20B/J25B, etc.), compatible with the standard oil port sizes of most hydraulic manifold blocks. It can be directly replaced, facilitating procurement and model selection.

Detailed Technical Parameters

Typical Application Fields

• Hydraulic Power Units/Hydraulic Pumps: Used for main oil circuit cut-off, pressure measurement point isolation, and accumulator isolation.
• Hydraulic Valve Groups/Manifold Blocks: Serves as the basic control valve of the system to realize on/off of each branch.
• Construction Machinery: Mounted on the main valve block to control the on/off of auxiliary oil circuits.
• Injection Molding Machines, Presses: Used to isolate executive components such as master cylinders and ejection cylinders for easy maintenance.
• Test Benches: Used for quick switching of test oil circuits.
