I. Product Overview
KHB and KHM type high-pressure ball valves are high-pressure valve equipment used in industrial piping systems, also known as hydraulic ball valves. This series of products is primarily used to cut off the fluid flow in hydraulic circuits and is widely applied in automated control systems within industrial sectors such as machine tools, system processes, mechanical equipment, steel and metallurgy, environmental protection, hydraulic oil circuits, and marine equipment. They are also suitable for fields including chemical engineering, petrochemicals, petroleum, papermaking, mining, power generation, liquefied gas, food processing, pharmaceuticals, water supply and drainage, municipal services, mechanical equipment support, electronics industry, and urban construction.
II. Performance and Structural Features
1. Performance Characteristics:
• Full-flow passage, high-pressure resistance, rapid opening and closing, and low torque.
• Leak-free operation, eliminating the need for manual readjustment of seals.
• Indicator slots for observing the on/off position, with limit pins and pads to define the switching positions.
• Low flow resistance loss, reliable sealing performance, and convenient operation.
• Surface-treated appearance for corrosion resistance.
2. Structural Features:
• Available in two forms based on structure: block type (KHB, DN04-25) and sleeve type (KHM, DN32-50).
• Mainly composed of a valve body, ball, valve stem, handle, and sealing device.
• The valve body is made of steel or stainless steel, with sealing elements available in nitrile rubber or fluororubber.
• Various handle forms and connection types such as M, G, LR, SR, PT, and NPT are provided.
III. Technical Parameters and Model Description
1. Basic Technical Parameters:
• Nominal diameter: DN06-50
• Pressure range: 1.6-32MPa (up to 500bar)
• Operating temperature: -30°C to +170°C (depending on the sealing material selected)
• Valve body material: Cast steel, forged steel, stainless steel
• Ball material: Steel, brass, stainless steel
2. Model Coding Rules:
• The model consists of multiple code segments, including series code, connection code, valve body material, ball material, operating temperature, sealing material, handle form, design sequence number, and surface treatment.
• For example: KHB-G1/2-1-2-01-X, where KHB is the series code, G1/2 is the connection code (ISO 228 internal thread), 1 represents the valve body material (steel), 2 represents the ball material (brass), 01 indicates the handle form (aluminum straight handle), and X represents the surface treatment (phosphating).
