Gas Line Shutoff Valves Overview

Specifications:
- The valves are normally open (NO) when de-energized and conform to EN 161 standards.
- They are available in various port sizes ranging from G1/2 to G2, with orifice sizes from 12 mm to 50 mm.
- The valves are made of brass with NBR seals and have a mass ranging from 0.4 kg to 4.5 kg.
- They operate at a differential pressure range of 0 to 500 mbar, depending on the model.
- The coil type is TM30, with a voltage of 200 V DC and power consumption of 8 W.
- The valves are connected to 230VAC through a plug with a built-in rectifier.

Design and Operation:
- The valves feature a low-noise design suitable for applications requiring quiet operation.
- They must be installed with a gas detector and are activated by an electrical impulse with a maximum duration of 5 seconds.
- The coil should not be continuously energized, with an ED (duty cycle) of 20%.

Model Dimensions:
- Model dimensions vary, with the smallest being PV4NO (1/2") and the largest PV8NO (2").

Installation Instructions:
- The preferred installation position is horizontal with the solenoid upright.
- The valve is supplied in a closed state and must be manually opened by pulling the button on top.
- Caution is advised to prevent solenoid damage by not energizing it for more than 5 seconds.
