Features piston actuator for v notch ball valve is the stroke length, but the price is expensive, so only for special occasion needs. It is also divided into two types of spring and without spring. Piston actuator acceptable higher operating pressure, air pressure and can be reached 0.5-0.7MPa, so its large output power.
Piston actuator with a spring itself can achieve a proportional action and the two movements, as compared with no spring piston actuator, can automatically create two forms of normally open and normally closed, and has broken a source of security, and improve in use security and reliability. Structure without a spring piston actuator is relatively simple, because do not have to overcome the spring reaction force, and therefore has a greater output power. It has two action and proportional action in two operation modes, in which the two sides of the piston action by the switching operation of the pressure to achieve, while the proportion of the action when the control signal is changed, on both sides of the piston to establish the necessary pressure difference, when the piston reaches the signal proportional to the stroke, the pressure on both sides by means of a double-acting piston V-ball locators, the piston maintained in a stable position.
