Linear Actuator

MASCOT spring cylinder linear actuator is a powerful, high-performance pneumatic actuator, which provides positive throttling or on-off operation to pneumatic control valves. Uniquely designed compact sized cylinders actuators accept supply pressures up to 150 psi, making very high thrusts available in a relatively compact unit. The basic 4 sizes cater to almost 85% of a plant’s requirement hence reducing the inventory & cost of maintenance spares.
The MASCOT spring cylinder linear actuator is fully field reversible for air to open or air to close action without additional parts; a spring provides reliable fail-safe operation.
Air is supplied to both the sides of the piston by the positioner providing very stiff and precise movement along with very high frequency response.
Salient FeaturesInherent Advantages
High thrust cylinder• Operating pressure of 150 psi (10.3 Bar) permitting substantially higher thrust capabilities than diaphragm actuators.
• Tighter valve shutoff
High Frequency Response• Double-acting configuration responds quickly to signal changes.
Lightweight & Compact• Substantially lighter and more compact than comparable linear diaphragm actuators.
• Offers ease of maintenance.
Wide choice• Four basic actuator sizes 25, 50 and 100 & 200 can handle thrust requirements for over 85 percent of valve sizes in a plant.
Least number of parts• 33% less parts than diaphragm actuators.
• Cost of wearing parts is 10% than compared to diaphragm actuators allowing low spare parts inventory and maintenance costs.
Excellent Positioning Accuracy• Powerful pneumatic stiffness allows a high pressure drop without plug slamming onto the seat due to air volume between the piston and the bottom of the cylinder.
Low Air Consumption• Cylinder design uses less supply air than comparable diaphragm actuators.
Longer Stroke• Longer strokes provide better process control. Size 25 spring cylinder linear actuators have a 11/2-inch (38 mm) stroke, in contrast to a 3/4-inch (19 mm) stroke on a comparable linear diaphragm actuator. Larger actuators have similar comparisons; stroke lengths are available up to 24 inches. This increases the rangability of MASCOT Control Valves.
Field Reversible• Failure mode is easily reversed without additional parts. Reduces inventory costs.
No Pressure Regulator Required• Cylinder actuators easily handle air supplies up to 150 psi (10.3 Bar) without a pressure regulator and can be operated with as little as 30 psi (2.1 Bar).
Simple Maintenance• Periodic maintenance is easy to perform since the spring cylinder actuator only requires the removal of three parts to access all internal parts.
