Festo PR-30-RT Detenting Mushroom Pushbutton

Technical Overview

30.5mm detenting mushroom pushbutton for SV/SVS/SVOS pneumatic valves. Features twist-to-release locking, 25N actuating force, and IP40 protection rating.

Key Features

Designed for seamless front-panel integration with Festo SV, SVS, and SVOS basic pneumatic valves
Detenting mechanism mechanically maintains the switched state until unlocked by a simple twist of the detent ring
Standardized 30.5 mm installation diameter enables quick and secure control panel mounting
Ergonomic actuation requires a consistent 25 N force for positive tactile feedback
Constructed with an IP40 rating to resist solid object ingress in controlled industrial environments
Vibrant red mushroom head provides high visibility for critical machine control operations

Industrial Applications

1. Emergency Pneumatic Circuit Isolation

Provides a distinct, detenting manual actuation point to lock out pneumatic flow during machine operation faults or maintenance intervals.

Problem Solved

Prevents accidental reactivation of downstream actuators by maintaining the pneumatic valve in a secure, locked state until deliberately twisted to release.

2. Test Bench State Control

Serves as the primary manual input for shifting basic control valves on fluid power test rigs, allowing technicians to engage and hold specific pressure states.

Problem Solved

Eliminates the need for continuous operator holding force during extended pneumatic testing cycles, reducing fatigue and ensuring consistent valve positioning.
