KHP Type (PKH Type) Plate Type High-Pressure Ball Valve, 304 Stainless Steel Plate Ball Valve KHP06 KHP10 KHP16

Product Overview

KHP type (also known as PKH type) flanged high-pressure ball valve is a basic on-off control component specially designed for hydraulic manifold systems (hydraulic stations, hydraulic valve groups). It completely abandons the traditional pipe connection method and is directly fastened with bolts to the valve block processed with corresponding oil ports through the plane and sealing ring at the bottom of the valve body. This design greatly simplifies the pipeline layout, saves installation space, and improves the neatness, rigidity, and reliability of the system. It is an ideal choice for realizing oil circuit isolation and pressure measuring point control in the hydraulic systems of construction machinery, injection molding machines, presses, and other equipment.

Detailed Product Features & Advantages

1. Flanged Connection, Core Advantages of Integration

• Maximized Space Saving: Directly installed on the surface of the valve block, no additional pipe joints and connecting pipelines are required. The system structure is extremely compact, and the number of leakage points is reduced.
• Rigid Connection with Shock Resistance: Bolt rigid connection has much better resistance to vibration and impact than threaded connection, which is very suitable for mobile equipment.
• Easy Installation and Maintenance: Convenient disassembly, facilitating the maintenance and cleaning of the valve block.
• Low Pressure Loss: The flow channel is optimized to transition smoothly with the oil port of the valve block, resulting in minimal flow resistance.

2. High-Pressure Design, Safe and Reliable

• Reinforced Valve Body: Adopting an integrally forged or high-strength cast valve body, it has a solid structure and excellent pressure-bearing capacity.
• Reliable Sealing: The bottom surface of the valve body adopts an O-ring seal, forming a static seal with the valve block plane to eliminate external leakage. The ball core and valve seat adopt metal or high-performance material seals to ensure zero internal leakage.

3. Stainless Steel Material, Coping with Harsh Environments

• 304 Stainless Steel: Provides excellent corrosion resistance, suitable for water-glycol, emulsion, seawater, and slightly corrosive oils, with a longer valve body service life.
• High Cleanliness: High surface finish, not easy to retain media, meeting the requirements of systems with high cleanliness standards.

4. Standard Bore, Global Interchangeability

• KHP06 (NG6): Suitable for small-flow control circuits.
• KHP10 (NG10): Suitable for medium-flow main oil circuits or branch circuits.
• KHP16 (NG16): Suitable for large-flow main oil circuits.
• Complies with international standards such as ISO 4401, and is compatible with the installation dimensions of mainstream brand valve blocks such as Rexroth, Parker, and Eaton, with strong interchangeability.
