Masoneilan Type 51/52/53 Pneumatic Piston Actuators meet requirements that exceed the typical capabilities of pneumatic spring diaphragm actuators. This Masoneilan Type 51/52/53 Pneumatic Piston Actuators is available in three different configurations:
Type 51: Double-acting cylinder (no springs), available with integral volume tank.
Type 52: Single acting cylinder, air to extend (extend stem) spring return
Type 53: Single acting cylinder, air to retract (retract stem) spring return
Masoneilan Type 51/52/53 Pneumatic Piston Actuators have following features:
Heavy internal guiding and support provides proper alignment of the dynamic components, delivering a rugged construction suited for the most demanding valve actuation requirements.
Standard construction options include double-acting without springs, as well as heavy mechanical spring-return for both air-to-extend and air-to-retract operation. Air volume in the cylinder is reduced in each design, providing high dynamic stiffness and improving speed of response.
The standard spring-return design includes separate spring cartridge subassemblies, which allow for safe pre-compression of the springs prior to final assembly into the actuator cylinder. The spring cartridge subassembly is also fully field reversible, which helps to reduce plant inventory.
Heavy guiding of the actuator stem results in excellent mechanical alignment of the key components, thus minimizing dynamic seal and sliding surface wear. This also helps to reduce overall operating friction, which enhances throttling control performance.
Baker Hughes has highly skilled service engineers available for start-up, maintenance and repair of our actuators and component parts. In addition,a regularly scheduled training program is conducted at the Training Center to train customer service and instrumentation personnel in the operation, maintenance and application of our control valves, actuators and instruments. Arrangements for these services can be made through your Baker Hughes representative or sales office. When performing maintenance, use only Masoneilan replacement parts. Parts are available through your local Baker Hughes representative or sales office. When ordering parts, always include Model and Serial Number of the unit being repaired.
