Air Flow Control Valve Types

Control valves operated through pneumatic actuators can be either i air to open.

Air flow control valve types.

Sometimes a float valve is also in the basin of cooling tower to control the level of water in cooling streams. Different types of flow control valves are available because each has a slightly different function. Single control two directionair flow control valves. A types of control valves based on action.

These are the most commonly used air flow control valves. Determining which flow control valve type is best for your particular situation depends on a host of criteria but the most commonly used types include gate valves globe valves pinch valves diaphragm valves and needle valves. Flow control choices for air valves include unidirectional one way bi directional two way or three way. The primary function of a flow control valve is to regulate the pressure of a flow of fluid in a pneumatic system.

Flow control valves are necessary components in a broad range of industries. A meter in flow control valve also known as a reverse flow control valve restricts the flow to an actuator. Flow control valves are essential for optimising system performance and relying on a flow passage or port with a variable flow area. They re often used to control the extension and retraction speed of an air cylinder at the same time.

Valves would also be needed for make up water lines in hvac system and cooling towers. They are designed such that if the air supply fails the control valve will be either fully open or fully closed depending upon the safety requirement of the process. We offer two types of air flow control valves. In a one way configuration the valve permits metered restricted flow in one direction and free flow in the reverse direction.

Most open valve automated control types ammonia based aeration control abac. Image via flickr by nalundgaard. Control six different outputs from a single source of airflow. Adjust airflow equally in both directions.

Multiple position single actionair directional control valves. A meter out flow control valve regulates the exhaust flow from an actuator. Their selection and placement within a pneumatic circuit will greatly affect the function of an actuator. Push in and rotate the dial to move between outlet ports and send airflow to a different output.

The range includes pneumatic and hydraulic control valves which are designed to cope with high flow rate working pressure and can be used for a variety of. These valves regulate the speed of airflow as it enters and exits equipment. These valves have one inlet port and six outlet ports. Ii air to close.

Cooling towers are another hvac equipments which require valves at inlet and outlet for flow control of cooling water.
