Product Description:
The Masoneilan pneumatic actuator diaphragms are OEM replacement parts specifically engineered for Type 87/88 spring-diaphragm actuators and Camflex eccentric rotary plug valve actuators. These diaphragms function as a crucial flexible barrier that transforms air pressure into mechanical force, fundamentally influencing the actuator’s response precision, seating force, and overall durability.
This product range includes the 035106040-716-0000 model designed for Camflex and eccentric rotary valve actuators. It is manufactured from Nitrile (Buna-N) material reinforced with polyester, offering superior resistance to oil and enhanced mechanical strength. Additionally, the models 010864-003-779, 010865-003-779, 010866-003-779, and 010867-003-779 cater to the 87/88 series actuators, featuring 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 performance, excellent leak-proof sealing, and strong protection against corrosive process fluids.
Designed to operate under pressures up to 150 psi and within a temperature range of -40°F to 180°F (-40°C to 82°C), these diaphragms are suitable for a wide variety of industrial control valve applications. Their multi-spring diaphragm actuator design allows for easy field reversibility and delivers dependable performance across both low and high pressure drop scenarios.
Features:
This product serves as an OEM replacement, perfectly compatible with Masoneilan 87/88 series as well as Camflex and eccentric rotary plug valve actuators. Its design ensures a direct fit, making it an ideal choice for seamless actuator maintenance and replacement.
Constructed from fiber-reinforced nitrile rubber, the material offers exceptional tensile strength and excellent resistance to oils. Additionally, it maintains dimensional stability even after repeated flexing, guaranteeing long-lasting performance under demanding operating conditions.
For the Camflex type, the incorporation of polyester reinforcement further improves its durability by increasing burst strength and extending fatigue life. This enhancement supports applications with rigorous cycling requirements, ensuring reliability throughout extensive use.
The diaphragm features a molded rolling design that minimizes friction, providing smooth and consistent travel. This design contributes to uniform actuation force across the entire stroke, enhancing overall actuator responsiveness and control precision.
Superior sealing capabilities prevent air bypass, which results in accurate pressure-to-thrust conversion. This high leak-proof sealing ensures optimal actuator efficiency and maintains reliable performance during operation.
Rated for pressures up to 150 psi, the diaphragm is compatible with standard pneumatic actuator supply pressures. It also operates effectively within a broad temperature range from -40°F to 180°F, accommodating diverse ambient and process environments.
The nitrile compound used is resistant to corrosion caused by oils, greases, and many fluids commonly encountered in control valve services. This corrosion resistance contributes to extended component life and reduced maintenance requirements.
Available in multiple diameters — 300 mm, 370 mm, 475 mm, and 550 mm — the diaphragm can be matched precisely to different actuator sizes and thrust needs. This range of options supports versatile application across various systems.
Proven in the field, this diaphragm design ensures reliable and stable actuation response, which helps prolong valve service life. Its durability and performance consistency make it a trustworthy component for maintaining efficient control valve operation.
