The PR 1/4″ single remote solenoid pilot has been designed for the control of VEM type diaphragm valves. PR 1/4″ can be installed on the interior wall of any control box or external part of the filter, located near the diaphragm valves. To install the PR 1/4″ it is necessary to drill a hole of 18.5 mm DN in the control box wall, leaving the pneumatic connection (PR 1/4″) outside the box. Anchor the solenoid pilot to the wall with the locknut. The pneumatic connection to the remotely piloted diaphragm valve is made with pneumatic pipe with an OD of 8 mm. The pneumatic pipe should not exceed a maximum length of 2 metres to ensure correct functioning of the pilot valve. The electrical connection is made inside the box by way of an IP65 connector with PG9 cable entry.
The PR 1/4″ solenoid pilot body is manufactured in brass and is available with solenoids with a full range of voltages.
Upon request the solenoid is also available in accordance with the ATEX Directive 94/9/CE, Zone 22 (Dust).
The PR 1/4″ is available with solenoid – 24DCX
(24 V DC/12 W) and DIN socket PLG9-ATEX.
