AM-55_Blocking valves G 1/8 ÷ G 1/2

Product catalog summary

Overview: This document provides technical specifications and operational details for unidirectional and bidirectional blocking valves used in pneumatic systems to ensure safety by blocking cylinder rods under specific conditions.

Specifications:

Max. Working Pressure: 10 bar
Ambient and Fluid Temperature Range: -20 to +180 °C
Fluid Temperature: 50°C max
Body Material: Die-cast zamak
Seals: Oil proof
Fluid: Filtered air, with or without lubrication

Functionality:

Unidirectional Blocking Valves: These valves block the cylinder rod when pressure fails. They allow air flow from port 2 to 1 in rest position and from 1 to 2 only upon receiving a control signal.
Bidirectional Blocking Valves: These valves block the cylinder rod when the controlling 5/2 valve is de-energized, achieving a 5/3 function. They allow air flow from 2 to 1 or 1 to 2 only upon receiving a control signal.

Applications:

Unidirectional valves are used to block cylinders when pressure fails, with opening 1 connected to the cylinder.
Bidirectional valves enable 3-position operation (closed centers) when used with a 5/2 valve, by connecting opening 2 to the cylinder and opening 1 to the 5/2 valve.

Product Variants:

Unidirectional and bidirectional valves are available with different port sizes (G 1/8, G 1/4, G 3/8, G 1/2) and capacities, with specific part numbers for each configuration.
