The following is a detailed introduction to the soft-sealed long-handled ball valve:
1. Main features
Excellent sealing performance: The soft sealing material can fit tightly with the ball to achieve zero leakage.
Easy to operate: The long handle design makes operation more labor-saving, especially suitable for large-diameter valves or occasions that require frequent operation.
Corrosion resistance: The soft sealing material has good tolerance to a variety of corrosive media.
Wide range of application: Suitable for water, oil, gas and corrosive media.
Easy maintenance: Simple structure, easy to disassemble and replace seals.
2. Application areas
Chemical industry: Suitable for the control of corrosive media such as acids, alkalis, and salts.
Water treatment: Used in water supply and drainage systems, sewage treatment, etc.
Food and medicine: Suitable for sanitary conditions, such as pure water, beverages, liquid medicines, etc.
Civil fields: Used for household water supply, heating systems, etc.
Industrial fields: Suitable for the control of low-pressure gas and liquid media.
3. Structure and working principle
Ball: The ball is a floating design. The medium pressure presses the ball to the valve seat on the outlet side to form a seal.
Valve seat: Made of soft materials (such as PTFE, rubber, nylon, etc.), it has good elasticity and sealing performance.
Valve stem: Connects the ball and the long-handled operating handle to transmit rotational force.
Long-handled handle: The long-handled design is easy to operate, especially in situations where large torque or long-distance operation is required.
Valve body: The outer shell of the valve, usually made of metal (such as cast iron, stainless steel, carbon steel) or plastic.
Sealing ring: Installed between the valve seat and the valve body to ensure sealing performance.
4. Selection suggestions
Media type: Select suitable soft sealing materials (such as PTFE, rubber) according to the corrosiveness, viscosity and other characteristics of the medium.
Pressure level: Select the pressure level of the valve according to the working pressure of the system.
Temperature range: Consider the temperature range of the medium and select soft sealing materials with suitable temperature resistance.
Operation mode: Select manual, pneumatic or electric operation mode according to needs.
Diameter selection: choose full-diameter or reduced-diameter design according to flow requirements.
5. Advantages
Zero leakage: Soft sealing materials can achieve bidirectional sealing with extremely low leakage rate.
Corrosion resistance: Suitable for a variety of corrosive media, extending the service life of the valve.
Easy to operate: The long handle design makes the operation more labor-saving and suitable for manual operation.
Low cost: Compared with metal-sealed valves, the manufacturing cost of soft-sealed long-handled ball valves is lower.
