Stainless steel pneumatic explosion-proof cut-off valve

Stainless steel pneumatic explosion-proof cut-off valveIntroduction:

Pneumatic floating ball valve is a valve whose opening and closing components (ball) are driven by the valve stem and rotate around the axis of the valve stem. Mainly used for cutting off or connecting media in pipelines, it can also be used for fluid regulation and control. The floating ball valve has a compact structure, reliable sealing, simple structure, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. It is suitable for general working media such as water, solvents, acids, and natural gas, and is also suitable for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. It has been widely used in various industries.

Stainless steel pneumatic explosion-proof cut-off valveFeatures:

1. Pneumatic ball valves have low fluid resistance and are one of the smaller types of valves in terms of fluid resistance. They can be opened and closed quickly and conveniently, powered by compressed air. Through the mechanical transmission of piston, rack, and gear, the valve stem rotates the ball body 0-90 ° with torque output at an angular stroke to quickly complete the opening and closing action or adjustment action. The core channel is flat and smooth, not easy to deposit media, and can be used for pipeline ball passing. Simple structure, light weight, and good sealing performance. It is the execution unit of instruments in the automation control system.
2. Using an electric pneumatic valve positioner, powered by electrical signals and compressed air, it receives a 0-10mA DC or 4-20mA DC current signal input from the control system. The regulator converts the compressed air into a gas source pressure signal input and output, and changes the rotation angle of the ball core to achieve proportional adjustment action.
3. Adopting electromagnetic directional valve and valve position feedback device, powered by AC220V or DC24V power supply voltage and compressed air, to achieve rapid two position cut-off control of fluid medium.
4. The pneumatic actuator adopts a piston type cylinder and a curved arm conversion structure, with a large output torque, small volume, and a fully sealed waterproof design with high protection level. The cylinder block adopts a mirror cylinder, oil-free lubrication, low friction coefficient, corrosion resistance, and has * durability and reliability. All transmission bearings adopt boundary self-lubricating bearings without oil lubrication to ensure that the transmission shaft is not worn.

Attachment options: Depending on different controls and requirements, the following attachments can be selected:
Feedback switch: also known as limit switch, remote feedback switch signal (optional explosion-proof).
Electromagnetic valve: Double acting with two position five way valve, single acting with two position three way valve (optional explosion-proof).
Triple component: capable of stabilizing the gas source, filtering, and adding lubricating oil to the cylinder.
Handwheel mechanism: Rotate the handwheel mechanism to manually open and close the valve.
Electrical locator: Input 4-20mA signal to achieve valve adjustment function.
