Product Description:
Masoneilan pneumatic actuator diaphragms are original equipment manufacturer (OEM) replacement parts specifically engineered for the 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, playing a vital role in defining the actuator’s response precision, seating force, and overall long-term durability.
This product line includes the model 035106040-716-0000 designed for Camflex and eccentric rotary valve actuators. Constructed from Nitrile (Buna-N) with polyester reinforcement, it offers outstanding resistance to oil and enhanced mechanical strength. Additionally, there are four models tailored for the 87/88 series actuators—010864-003-779, 010865-003-779, 010866-003-779, and 010867-003-779—with nominal diameters of 300 mm, 370 mm, 475 mm, and 550 mm, respectively. These diaphragms are molded from fiber-reinforced nitrile rubber, ensuring consistent actuation response, excellent sealing to prevent leaks, and robust resistance against corrosion from process fluids.
Designed to handle operating pressures of up to 150 psi and to operate effectively within a temperature range from -40°F to 180°F (-40°C to 82°C), these diaphragms are suitable for a wide variety of industrial control valve applications. Furthermore, the multi-spring diaphragm actuator design facilitates field reversibility and guarantees reliable operation across low to high pressure drop environments.
Features:
This product serves as an OEM replacement, designed to be a direct substitute for Masoneilan 87/88 series as well as Camflex and eccentric rotary plug valve actuators. It ensures compatibility and straightforward installation without the need for modifications.
Constructed from fiber-reinforced nitrile rubber, the material offers exceptional tensile strength, outstanding oil resistance, and excellent dimensional stability even under repeated flexing conditions. This combination ensures durability and long-term performance.
For the Camflex type, polyester reinforcement is incorporated to significantly enhance the burst strength and improve fatigue life, making it ideal for applications requiring demanding cyclic endurance. This reinforcement supports consistent operation throughout rigorous cycles.
The molded rolling diaphragm design provides low friction and smooth movement, resulting in a uniform actuation force across the entire stroke. This feature contributes to precise control and reliable actuator function.
With high leak-proof sealing, the product prevents air bypass effectively, ensuring accurate pressure-to-thrust conversion. This sealing capability maintains operational efficiency and prevents performance degradation over time.
Rated for pressures up to 150 psi, this diaphragm is suitable for standard pneumatic actuator supply pressures. Its broad operating temperature range, from -40°F to 180°F, allows it to perform well in various ambient and process conditions.
The nitrile rubber compound offers excellent corrosion resistance against oils, greases, and a wide variety of process fluids commonly encountered in control valve service environments, ensuring longevity and reduced maintenance requirements.
Available in multiple diameters—300 mm, 370 mm, 475 mm, and 550 mm—this product can accommodate different actuator sizes and thrust demands, providing flexibility for diverse application needs.
Field-proven reliability is a hallmark of this design, which is engineered to maintain a stable activation response and extend the operational life of the valves, resulting in dependable performance in the field.
