KHB Series 304 Stainless Steel High-Pressure Ball Valve, H-Type Interface 25SR 18LR Ball Valve, 24° Cone Pipe Strong Seal

Product Overview

The KHB Series High-Pressure Ball Valve is a professional valve specially designed for ultra-high pressure hydraulic systems. It adopts a 304 stainless steel valve body, equipped with a standard Type H ferrule interface and a 24° taper sealing structure. The product provides two interface types: 25SR (straight-through) and 18LR (right-angle), featuring excellent pressure resistance and sealing reliability. It is widely used in construction machinery, hydraulic equipment, and industrial fluid control fields.

Core Product Advantages

1. Excellent Sealing Performance

• 24° Taper Seal: Adopts a precision-machined metal-to-metal hard sealing structure to achieve bidirectional zero leakage
• Ultra-High Pressure Design: Pressure-bearing capacity reaches 31.5MPa, passing a 1.5x pressure safety test
• Wear-Resistant Design: The ball surface undergoes hardening treatment, resistant to erosion and with a long service life

2. Reliable Connection Method

• Type H Ferrule Interface: Provides a firm connection with excellent anti-vibration performance
• Dual Sealing Guarantee: Ferrule seal + taper seal to ensure no leakage
• Standard Interface: Complies with international standards and has strong interchangeability

3. Advantages of Stainless Steel Material

• Corrosion Resistance: 304 stainless steel provides excellent corrosion resistance
• High Strength: The valve body has high strength and is resistant to high-pressure impact
• Wide Applicability: Suitable for various hydraulic media

4. Diverse Structural Forms

• 25SR Straight-Through Type: Low flow resistance and minimal pressure loss
• 18LR Right-Angle Type: Saves installation space and enables flexible layout
