Key Features and Benefits
1. Reliable Sealing and Excellent Compatibility
Bidirectional Sealing Design: Allows for bidirectional media flow, eliminating installation direction restrictions and simplifying system piping.
Material Science Matching: The core ball uses POM sealing, balancing wear resistance and sealing performance; the dynamic seal uses NBR, widely compatible with hydraulic oil, lubricating oil, and water-glycol, ensuring long-term reliable sealing in various applications.
2. Designed for High Pressure and High Efficiency
Ultra-High Pressure Bearing: Rated pressure up to 500 bar, easily handling extreme high-pressure conditions in construction machinery, mining equipment, and other applications.
Full Flow Path Unobstructed Design: Provides a flow path essentially identical to the pipe inner diameter when open, resulting in minimal pressure drop, effectively reducing system energy consumption and improving the efficiency of the entire hydraulic system.
Fast Opening and Closing and Anti-Cavitation: The unique structural design enables rapid valve opening and closing, and effectively prevents cavitation caused by sudden pressure changes, protecting downstream pipes and equipment.
3. Robust and Durable with Convenient Installation
All-Carbon Steel Robust Valve Body: The main structure is made of high-strength carbon steel for long-lasting durability.
Standardized Interface: Uses SAE J518C standard flanges, seamlessly connecting with mainstream hydraulic components for easy and quick installation and maintenance.
Galvanized Surface Treatment: Enhances corrosion resistance, suitable for indoor and outdoor industrial environments with varying humidity levels.
Application
The superior performance of the KHB series valves makes them ideal for the following industries:
Construction and Agricultural Machinery: Hydraulic control systems for equipment such as excavators, loaders, and tractors.
Mining Equipment: High-pressure hydraulic systems for rock drilling rigs, hydraulic supports, and mining trucks.
Energy Industry: Instrumentation and control pipelines for natural gas compression and transmission equipment.
Industrial Hydraulic Power Stations: Switching and control of high-pressure power units in various manufacturing plants.
FAQ
Q1: What does SAE J518C interface mean?
A1: SAE J518C is one of the internationally recognized standards for four-bolt flange connections in hydraulic systems. Using this standard means our valves can be easily integrated into existing hydraulic lines that conform to the same standard, ensuring sealing and strength at the connection, greatly improving installation compatibility and reliability.
Q2: What is the difference between POM and NBR sealing materials?
A2: This is an optimized choice for different functions. POM has high hardness and wear resistance, used as the main ball seal, and can withstand the friction and high-pressure compression of frequent opening and closing. NBR has good elasticity and strong oil resistance, used as the dynamic seal for valve stems and joints, effectively compensating for minor deformations and ensuring no leakage at rotation and connections.
Q3: Can this valve be used with natural gas?
A3: Yes. However, please confirm with us before using it with specific media such as natural gas. While the basic sealing material is suitable, for flammable and explosive gases, it may be necessary to verify the complete compatibility of the material or provide special fireproofing options to ensure absolute safety.
