High-Pressure Plate Ball Valve KHP Type (PKH Type) KHP-10 KHP-16 KHP-20 KHP-25 KHP-32

Product Overview

KHP type (also known as PKH type) high-pressure flanged ball valve is one of the core basic components of modern hydraulic manifold systems. It is directly fixed on the machined surface of the hydraulic manifold block through the flat seal (O-ring) and bolts at the bottom of the valve body, realizing the on-off control of the oil circuit. This design completely eliminates traditional pipe joints and connecting pipelines, making the hydraulic system structure more compact and neat, and greatly improving the rigidity and pressure resistance reliability of the system. It is widely used in construction machinery, injection molding machines, hydraulic stations and other equipment as a functional valve for main oil circuit cut-off and pressure measuring point isolation.

Detailed Product Features & Advantages

1. Flanged Connection, Core Advantages of Integration

• Extreme Compactness: Directly mounted on the surface of the valve block, it greatly saves space, especially suitable for complex multi-valve groups with intricate structures.
• Zero Leakage Potential: There is a flat static seal (O-ring) between the valve body and the valve block, which fundamentally eliminates the hidden danger of interface leakage compared with threaded connections.
• Strong Vibration Resistance: Rigid bolt connection ensures no loosening under high-vibration working conditions, with reliability far exceeding that of tubular connections.
• Easy Maintenance: Convenient disassembly facilitates the cleaning and maintenance of the valve block.

2. Full Bore Range, Comprehensive Flow Coverage

• KHP-10 (NG10): Suitable for small-flow occasions such as pilot control circuits and lubrication systems.
• KHP-16 (NG16): Applicable to medium-flow branches and is one of the most commonly used models.
• KHP-20, KHP-25, KHP-32: Suitable for main oil circuits with large flow rates, such as main pump outlets and large-flow actuators.

3. High-Pressure Design, Safe and Stable

• Reinforced Valve Body: Adopts high-strength steel forging or precision casting, with a solid structure and excellent pressure resistance.
• Reliable Sealing: The ball core and valve seat use metal hard seals or high-performance composite materials, which are resistant to high-pressure erosion and have a long service life.

4. Standard Interface, Globally Universal

• Mounting dimensions, bolt hole spacing, O-ring grooves, etc., comply with internationally common standards (such as ISO 4401), ensuring seamless replacement and installation with valve blocks of mainstream brands such as Rexroth, Parker, and Eaton.
