NY Series Linear Pneumatic Actuators

DESCRIPTION

The NY series linear pneumatic actuators represents a broad range of field proven, it suitable for automating most types of rising stem valves in safety shutdown and control applications. The NY actuators are manufactured in accordance with strict quality standards and assure reliability and safety in your specific service. This catalog lists standard models intended to cover a wide range of sizing applications. Custom designed models are also available for specialized thrust or stroke requirements.

The NY actuators are designed to operate most types of wedge gate valves, slab gate valves,knife gate valves, globe valves, tank valves and rising stem ball and plug valves. Other applications include louvers.

FEATURES

MANUAL OPERATE

	Manual Jackscrew Override The NY series linear pneumatic actuators are available with a unidirectional manual jackscrew handwheel override for emergency use when plant air or power gas is unavailable. The override can also be used to hold the actuator in a particular position. For models where a jackscrew override is not feasible due to high thrust requirements, dimensional clearance or lack of accessibility, a manual hydraulic override is available.
	Hydraulic Manual Override The NY series pneumatic actuators are also available with a manual hydraulic override(HY), bidirectional for double-acting and unidirectional for spring-return, type 'FS' or 'FR'. The 'HY' override can also be used as a dampener for precise control of the cylinder speed.
	Tandem Power Cylinder The actuators can output a greater thrust, and it has compact structure .
