Proportional valve is designed to control the flow of electronic control of the throttle, structural changes can also be achieved through pressure control. Airsky offer a range of functions including open and closed loop control, fail freeze and ATEX options, but high performance price ratio.
The 5 port VER2000 electro-pneumatic proportional valve can be used to switch and actuate a cylinder and to perform stepless pressure control of port A through electric signals. The VER2000 (direct operated type) is available with 1/4 or 3/8 port size. The VER4000 (internal pilot type) and the VER4001 (external pilot type) are available with 3/8, 1/2 or 3/4 port size. Thread types include Rc, G, NPT or NPTF. The VER is also available without a sub-plate.
A proportional control valve system provides the ability to infinitely control the position of the internal spool assembly which increases or decreases the amount of flow or pressure being released from the valve. AIRSKY offers 2 types of proportional control valves, a pressure type VEP which controls secondary pressure by varying the current through the solenoid, and a flow rate type VEF which controls air flow by varying current through the solenoid.
PVQ30 compact proportional solenoid valve, this construction enables low leakage, while de-energized. PVQ series has been used in applications such as air blow, flow control, hand piece control for dental unit and other respiratory equipment, as well as, cooling for laser machinery etc.
PVQ13 compact proportional solenoid valve, was designed by AIRSKY with a direct poppet construction. This construction enables low leakage, while de-energized. PVQ series has been used in applications such as air blow, flow control, hand piece control for dental unit and other respiratory equipment, as well as, cooling for laser machinery etc.
The VPCF porportional flow control valve satisfies the highest requirements in terms of dynamic response, repetition accuracy and characteristic curve linearity. Extremely short cycle times mean that unit numbers can be increased and therefore costs can be cut substantially.
