Electric stainless steel ball valve only need to rotate 90 degrees of operation and a small turning moment can be closed tight. The completely equal body cavity provides a medium-sized, straight-through runner with low resistance. By the electric (or pneumatic) actuator and ball valve body part, which is connected by the bracket and the connecting shaft. Shows the maximum allowable maximum operating pressure of the ball valve at maximum and minimum operating temperatures. With PTFE or RTFE seat and seals, the operating temperature should be between -290C and 2000C. Other types of valve seat and seal operating temperature, should be KI factory inspection. The nominal pressure rating (PN) of the valve indicates the maximum working pressure of the valve at normal temperature.
Operation and use
1) Before operation, make sure that the piping and valves have been flushed. The company is located in:
2) The operation of the valve drives the valve stem to rotate according to the input signal of the actuator: when the valve is rotated 1/4 turn (900) forward, the valve is shut off. The valve opens when rotated 1/4 turn (900) in the reverse direction. The company is located in:
3) The valve is open when the direction arrow of the implementing agency is parallel to the pipeline; the valve is closed when the indicating arrow is perpendicular to the pipeline.
Electric stainless steel ball valve use completely equal body cavity for the medium to provide resistance is small, through the runner. Electric stainless steel ball valve is characterized by its compact structure, easy operation and maintenance, suitable for water, solvents, acids and natural gas and other general working medium, but also for bad working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene . Electric stainless steel ball valve body can be a whole, it can be combined.
Electric stainless steel ball valve precautions see their corresponding instructions. The company is located in:
1) Remove the protective cap on both sides of the flange and flush it with the valve fully open. The company is located in:
2) Before installation, it should be tested according to the required signal (electric or gas) (to prevent the use of vibration due to transport performance), after passing the line can be installed. The company is located in:
3) Flush and remove residual contaminants from clean pipelines (these may cause damage to the seat and ball) before connecting to the pipe. The company is located in:
4) During the installation, please do not use the actuator part of the valve as lifting lifting point to avoid damaging the actuator and accessories. .
5) This type of valve should be installed in the pipe horizontal or vertical direction. The company is located in:
6) The pipe near the installation point can not be lowered or subjected to external force. Pipe supports or supports can be used to eliminate the pipeline deviation. The company is located in:
7) After connecting with the pipe, cross-fasten the flange connecting bolt with the specified torque.
