1. No pin butterfly valve features
Pinless butterfly valve adopts bidirectional hard seal or one-way soft seal structure, pinless design makes the butterfly valve has little friction when opening and closing, with the following characteristics:
(1) Simple structure, flexible opening and closing, convenient installation, greatly reduce the valve running friction and wear, reduce equipment maintenance costs;
(2) reliable sealing, two-way sealing or one-way sealing structure, high sealing performance;
(3) small flow resistance, fluid resistance is small, in large caliber and low pressure loss occasions have superior performance;
(4) Good damping performance, prevent water percussion, ensure the safety of equipment.
2. No pin butterfly valve operating environment
Pinless butterfly valves are suitable for the following environments:
(1) Temperature range: -40℃~+200℃;
(2) Pressure range: 0.6MPa~6.4MPa;
(3) Media: water, sewage, oil, gas, chemicals, etc.;
(4) Industries: petroleum, chemical, metallurgy, electric power, pharmaceutical, food, etc.
3. Notes for the purchase of pinless butterfly valve:
(1) Confirm the specifications, models, materials and sealing structure of the pinless butterfly valve;
(2) Check whether the working pressure and temperature range of the pinless butterfly valve meet the requirements;
(3) Confirm whether the sealing structure of the pinless butterfly valve can meet the requirements;
(4) To understand the reputation of pinless butterfly valve manufacturers, after-sales service is perfect, the purchase of guaranteed products.
4. No pin butterfly valve maintenance
(1) Check the seal and corrosion of butterfly valve regularly and deal with it in time;
(2) When replacing the sealing material, the material suitable for the medium should be selected and the lubricant should be used reasonably;
(3) Check whether the connecting bolt of the valve is loose and remove dust and foreign matter;
(4) Ensure that the working environment of the pinless butterfly valve is clean to prevent the intrusion of impurities;
(5) Regularly clean the internal parts of the pinless butterfly valve and replace the badly worn parts;
(6) The electrical system maintenance of pinless butterfly valves must be carried out by professionals.
