Sanitary diaphragm valve three-quarter view with pneumatic actuator

Sistemas de Utilidade de Cleanroom

Válvula de diafragma sanitário

A pneumatically operated 316L diaphragm valve that isolates the actuator from sterile and high-purity process media.

Actuator isolated from process media
Forged 316L hygienic body
Drainable straight-through flow path

Introdução do produto

The sanitary diaphragm valve controls high-purity media through a flexible diaphragm that seals against the body weir while separating the actuator from the wetted flow path. Its compact straight-through body, polished internal surface and configurable pneumatic actuator suit automated clean-utility and sterile-process piping.

Preocupações do produto do cliente

Correct valve performance depends on diaphragm compatibility, actuator sizing, installation angle and a flow path that can drain and clean as intended.

Process media reaches actuator componentsUse the diaphragm as a continuous barrier between the wetted body and actuator mechanism.

Diaphragms fail prematurelyMatch diaphragm material and closing force to temperature, pressure, chemistry and sterilization cycles.

Water remains after system drainageInstall the valve at the body-specific drain angle with correctly oriented tube runs.

Valve status is unclear to automationAdd a compatible position indicator or control head with open and closed feedback.
