(1) Before the pneumatic valve is installed and used, the valve must be inspected before installation and switch operation test. It can only be installed and used under normal operating conditions.
(2) The installation of the pneumatic valve should make the valve concentric with the pipeline flange as much as possible, and support it. The ball valve cannot be subjected to other external forces, so as to avoid damage to the middle seal of the valve and deformation of the valve. The valve switch is ineffective and the valve is damaged and cannot be used.
(3) To ensure that the power source provided by the balloon valve and pneumatic components must be clean and free from oil and water as much as possible. Cleanliness should be less than 0.4 microns.
(4) Before connecting to the air source, it is necessary to clean the air supply pipeline, air source interface and switch and other devices to prevent failure due to the unclean pipeline and the dirt and sediment rushing into the pneumatic actuator unit.
(5) For the connection of pneumatic actuators, solenoid valves, positioners, filters, pressure reducing valves, etc., copper pipes or nylon pipes can be used. In order to prevent dust and reduce noise, mufflers or mufflers should be installed at the exhaust port. flow valve.
(6) After installation, the pneumatic valve should be tested, the pneumatic actuator should be pressurized to the rated value, the pressure is 0.4 ~ 0.7mpa, the switching test of the pneumatic ball valve should be carried out, and the opening and closing of the valve should be observed. It should rotate flexibly without jamming. If the switch is blocked, the air pressure can be increased, and the valve can be adjusted to the flexible switch by repeating the switch.
(7) When installing and debugging the switch-type pneumatic valve, first use the manual device (manual button on the solenoid valve) to debug, and then debug after the operation is normal.
(8) The pneumatic valve should be regularly maintained at the rotating part of the valve stem, and oil (oil) should be refueled once every three months. Regularly discharge water and sewage to the pneumatic actuating unit and the air filter used in conjunction with it. Under normal circumstances, it should be checked once every six months and overhauled once a year.
