Masoneilan 010864-003-779 Pneumatic Control Valve Actuator Diaphragm Diameter 300mm NBR Reinforced Rubber For 87 88 Series Actuator Petrochemical Process Repair Part

Product Description:

These Masoneilan pneumatic actuator diaphragms are original equipment manufacturer (OEM) replacement parts, specifically designed for the Type 87/88 spring-diaphragm actuators as well as Camflex eccentric rotary plug valve actuators. Serving as a vital flexible barrier, the diaphragms convert air pressure into mechanical thrust. This conversion directly influences the actuator’s response precision, seating force, and overall long-term reliability.

The product range features the model 035106040-716-0000, tailored for Camflex and eccentric rotary valve actuators. This diaphragm is constructed from Nitrile (Buna-N) and reinforced with polyester, providing excellent resistance to oils along with strong mechanical durability. In addition, the models 010864-003-779, 010865-003-779, 010866-003-779, and 010867-003-779 are designed for the 87/88 series actuators, coming in nominal sizes of 300 mm, 370 mm, 475 mm, and 550 mm respectively. These are molded using fiber-reinforced nitrile rubber, which ensures consistent actuation performance, superior sealing to prevent leaks, and robust resistance against corrosion caused by process fluids.

These diaphragms are capable of operating at pressures up to 150 psi and can withstand temperatures ranging from -40°F to 180°F (-40°C to 82°C). This makes them well-suited for a wide variety of industrial control valve applications. Moreover, the multi-spring diaphragm actuator design provides field reversibility and dependable operation across a broad spectrum of pressure drop conditions, from low to high.

Features:

The OEM replacement fit is designed as a direct substitute for Masoneilan 87/88 series actuators as well as Camflex and eccentric rotary plug valve actuators. This ensures seamless compatibility and hassle-free installation without the need for modifications.

Manufactured from fiber-reinforced nitrile rubber, the diaphragm offers excellent tensile strength and superior oil resistance. Its dimensional stability remains intact even after repeated flexing, making it highly durable in demanding applications.

For Camflex-type actuators, polyester reinforcement is incorporated to improve burst strength and fatigue life. This enhancement allows the diaphragm to meet rigorous cycle requirements and perform reliably over extended periods.

The molded rolling diaphragm design delivers low friction and smooth travel throughout the entire stroke. This ensures consistent actuation force, contributing to optimal valve control and responsiveness.

With high leak-proof sealing capabilities, the diaphragm effectively prevents air bypass. This feature enables precise pressure-to-thrust conversion, enhancing actuator efficiency and reliability during operation.

Rated for pressures up to 150 psi, this diaphragm is suitable for most standard pneumatic actuator supply pressures. Its operational temperature range spans from -40°F to 180°F, accommodating a wide variety of ambient and process conditions.

The nitrile compound composition offers strong corrosion resistance against oils, greases, and many process fluids commonly encountered in control valve services, thereby extending the component’s lifespan.

Available in multiple diameter sizes—300 mm, 370 mm, 475 mm, and 550 mm—the diaphragm can match different actuator sizes and meet various thrust requirements effectively.

Field-proven for reliable performance, the diaphragm is engineered to maintain stable actuation response and significantly extend the service life of valves in diverse operating environments.

Applications:

The Masoneilan 87/88 spring-diaphragm actuators offer replacement diaphragms suitable for both air-to-open and air-to-close configurations. These are specifically designed for globe control valves to ensure efficient and reliable operation.

Camflex eccentric rotary plug valves utilize actuator diaphragms to provide precise rotary valve control, commonly used in various process industries. These diaphragms help maintain optimal performance and durability in demanding environments.

Control valves designed for low to high pressure drops rely on these diaphragms for dependable actuation. They ensure accurate positioning and sufficient seating force, which are critical for maintaining process control and valve integrity.

In the oil and gas industry, diaphragm replacements are essential for control valves operating across upstream, midstream, and downstream processing stages. These components contribute to the reliable and safe functioning of critical flow control systems.

Chemical and petrochemical facilities benefit from corrosion-resistant diaphragms that can withstand aggressive media environments. This resistance helps extend the lifespan of control valves used in harsh chemical conditions.

Power generation plants utilize these diaphragms for the maintenance of steam and water control valve actuators, ensuring consistent and efficient operation of vital systems within the plant.

Across general industrial flow control applications, routine maintenance and overhaul of pneumatic control valve actuators often include diaphragm replacement. This practice supports ongoing reliability and optimal performance in diverse industrial settings.
