Design characters:
This corrosion resistant butterfly valve is a separated style with the PTFE liner ring inside. It can be fit for various corrosive and dangerous medium. Between the liner ring and the valve is the back liner which is made of high-elasticity rubber. The liner ring disc adopts the double spherical surface sealing structure which is used to guarantee the reliable closing and sealing performance. with the ascendant design, it will be safety and no leakage during the long-term use.
Performance:
Nominal Diameter: DN40-DN1200
Nominal Pressure PN (MPa):
1.0, 1.6, 2.0, 2.5
Testing pressure (water) PS (MPa)
Body seat: 1.5 times rated pressure
Seat test: 1.1 times rated pressure
Here is the features:
1. Structure simple is compact, stable positioning, and the weight is light.
2. Designs reasonably, the assembling and dismantling and installation is easy, to be advantageous.
3. Minimized operating torque. Lever, gear, pneumatic and electric actuators can be chosen.
3. Rubber backed seat with stable valve torque. No leakage under the rated pressure.
4. Special design, high flow rate and low flow resistance.
Application:
1. These products are mainly used for pipeline flow, pressure and temperature control of various industrial automation productiong, for example: Electricity, petrifaction, metallurgy, environmental protection, energy management, fir-fighting systems.
2. Simultaneously they have good fluid control properties, and can operate simply.
3. They are not only widely used in general industries as petroleum, coal gas, chemical engineering, water treatment, but also used in the cooling water system of thermal power plant.
