How to Select the Pneumatic Angle Seat Vave ?

Pneumatic angle seat valve can be divided into four forms:

First: Single Acting Normally Closed Type

Working principle: According to the spring return to achieve the function of closing the valve. only one air pipe needs to be installed during work, the vent valve is opened, and the lost gas valve is automatically closed. It is easy to install and use under normal pressure and normal temperature.

Second: Single Acting Normally Opened Type

Working principle: According to the ventilation, the valve is dosed. Only one air pipe is required to be installed during operation. The ventilation valve is closed and the lost gas valve is automatically opened. lt can be used in the case of high temperature and high pressure and the need to open the valve for a long time.

Third: Double Acting with Spring Close Type ( Recommend)

Working principle: According to the spring return to achieve the function of closing the valve. only one air pipe needs to be installed during work, the vent valve is opened, and the lost gas valve is automatically closed. It is easy to install and use under normal pressure and normal temperature

Fourth: Double Acting (Free State)  

Working principle:

According to the ventilation control valve switch, two air pipes need to be installed during operation, and it is used when the pressure of the control actuator is low. The user can open the valve according to the use situation and belong to the normally open state. The double-acting free state can prolong the life of the valve under the condition of low pressure and low temperature.

Pneumatic Angle Seat Valve, Conventional , Actuator Size Head Selection :

The minimum control pressure of the normally closed actuator is 0.4MPa. When the medium pressure is higher than the control pressure and the control pressure is only 0.4 MPa, the valve will not open. ln this case, use a large head and increase the actuator to 80. And 100, normally open type, under the installation of the waterproof hammer, the medium pressure is higher than the control pressure of the actuator, you need to use a large head to increase the actuator. For unconventional installation, contact us to select the model according to the actual pipeline medium pressure. temperature and pressure control.

According to user requirements can be equipped with accessories: solenoid valve, limit switch, pressure reducing valve filer, proximity switch, signal feedback, positioner. etc. all specification can be customized according to user use, if necessary, can send professionals, site design and installation.

The angle seat valve maintains the flow rate and saves space. The pilot angle seat valve operated by a spring-actuated single-acting actuator mechanism can be widely used in short-time and frequent start-up. Pneumatic control can accurately control the flow of gas and liquid. and can achieve accurate temperature control, drop liquid addition and other requirements, Warm sterilizaton uses angle seat valve to control steam volume to accurately control temperature
