Description
The Fisher 2E791902202 Diaphragm is a flexible control element measuring 30 inches, constructed from NBR/NYL material combination and identified with 17E44 specification. It is used for regulating pressure response and movement transfer in control assemblies. The diaphragm operates by flexing under pressure variation, translating force changes into mechanical movement for valve or actuator control. Installed inside pneumatic or mechanical control units within HVAC systems, it is fitted into the diaphragm housing and sealed within the assembly during setup. This arrangement supports accurate pressure response, contributes to steady control action, and maintains uniform system regulation during continuous operation cycles.
