Is the MRF PTC plastic pneumatic throttling valve, for actuator, PUSH-LOCK series adjustable under pressure and does PUSH-LOCK prevent accidental rotation?

Yes. The MRF PTC plastic pneumatic throttling valve, for actuator, PUSH-LOCK series is adjustable under pressure via its knob . itâs designed for in-service flow regulation in pneumatic actuator connections (working pressure up to 10 bar). The PUSH-LOCK feature provides a locking action on the adjustment knob: you push to lock/unlock, which prevents accidental rotation once engaged, while still allowing intentional readjustment when released.

Can the MRF PTC plastic pneumatic throttling valve, for actuator, PUSH-LOCK series be installed in confined spaces without removing the PUSH-LOCK coupling?

Yes - the MRF PTC plastic pneumatic throttling valve, for actuator, PUSH-LOCK series can be installed in confined spaces without removing the PUSH-LOCK coupling, provided there is enough clearance to engage the plugâin coupling and operate the adjustment knob. The PUSHâLOCK coupling is designed for easy disassembly of pneumatic hoses, but it remains functional while mounted; you only need access to press the lock and to turn the knob. Ensure sufficient room to access the coupling and the knob within the temperature range (â10Â°C to +50Â°C) and for pressures up to 10 bar.

Can the MRF PTC plastic pneumatic throttling valve, for actuator, PUSH-LOCK series be used with different hose diameters without adapters?

No. the MRF PTC plastic pneumatic throttling valve, for actuator, PUSH-LOCK series cannot be used with different hose diameters without adapters. The product is offered in specific sizes (1/8â³ and 1/4â³) and is equipped with a matching plug-in coupling designed for those hose diameters. Using hoses of a different outer/inner diameter would prevent proper, leak-free connection and could compromise the PUSH-LOCK coupling, pressure rating (up to 10 bar) and safe operation. To use a different hose size you need a suitable adapter or a valve version matching the hose diameter.
