Product Description:
The Masoneilan pneumatic actuator diaphragms are OEM replacement parts specifically engineered for Type 87/88 spring-diaphragm actuators as well as Camflex eccentric rotary plug valve actuators. These diaphragms function as the essential flexible barrier that transforms air pressure into mechanical thrust. This conversion is vital as it directly impacts the actuator’s accuracy in response, the force applied when seating, and the overall durability and reliability over time.
The product lineup features the 035106040-716-0000 model designed for Camflex and eccentric rotary valve actuators. This diaphragm is made from Nitrile (Buna-N) reinforced with polyester, which offers superior resistance to oil and enhances mechanical strength. Additionally, the 010864-003-779, 010865-003-779, 010866-003-779, and 010867-003-779 models cater to the 87/88 series actuators, with nominal diameters of 300 mm, 370 mm, 475 mm, and 550 mm respectively. These are fabricated from fiber-reinforced nitrile rubber, ensuring consistent actuation response, excellent leak-proof sealing, and high resistance to corrosion from process fluids.
These diaphragms are capable of handling operating pressures up to 150 psi and function effectively within a temperature range from -40°F to 180°F (-40°C to 82°C). Such specifications make them well-suited for a wide variety of industrial control valve applications. Furthermore, the multi-spring diaphragm actuator design provides the advantage of field reversibility and guarantees dependable performance across both low and high pressure drop conditions.
Features:
This product serves as an OEM replacement that directly fits Masoneilan 87/88 series as well as Camflex and eccentric rotary plug valve actuators. It is engineered to seamlessly replace existing components without requiring modifications.
Constructed from fiber-reinforced nitrile rubber, the material offers exceptional tensile strength, excellent resistance to oils, and retains its dimensional stability even under repeated bending or flexing conditions.
For the Camflex type, polyester reinforcement is incorporated to significantly improve burst strength and extend fatigue life, making it suitable for applications demanding frequent cycling and durability.
The molded rolling diaphragm design contributes to low friction operation and smooth travel throughout the actuator stroke. This ensures consistent actuation force, which enhances overall performance and control accuracy.
The product features high leak-proof sealing capabilities that effectively prevent air bypass. This tight sealing maintains precise pressure-to-thrust conversion, which is critical for reliable pneumatic actuator function.
With a pressure rating of up to 150 psi, it is compatible with standard pneumatic actuator supply pressures, ensuring versatility across a broad range of systems.
This component operates efficiently across a wide temperature range, from -40°F to 180°F, accommodating various ambient and process environments without compromising performance.
The nitrile compound provides excellent corrosion resistance against oils, greases, and many other process fluids commonly encountered in control valve applications, thereby enhancing longevity.
Available in multiple diameter options—300 mm, 370 mm, 475 mm, and 550 mm—it is designed to match different actuator sizes and thrust requirements, providing flexibility for diverse installation needs.
Proven in the field, this product is engineered to deliver reliable and stable activation response, ultimately extending the service life of valves and minimizing maintenance requirements.
