SMC VHS40-D Series Pressure Release Valve, 10 Bar Maximum Operating Pressure, 14098L/min Maximum Flow Rate - VHS40-F06-D

This pressure release valve is a three-port pneumatic valve designed to control supply and exhaust flow in industrial automation systems. It provides a manual rotary-knob actuation with a two-step push-and-turn locking function for safe switching and can be mounted with an optional bracket or built-in silencer for exhaust management.

Features & Benefits

• Maximum operating pressure 10 bar improves system protection
• High flow capability 14,098 L/min supports large-volume venting
• Polybutylene terephthalate body reduces weight and resists heat
• Rotary knob operation with red control offers clear status indication
• Locking holes allow padlock securing to prevent accidental supply
• Rated for −5 to +60°C for typical factory environments

Applications

• Suitable for isolating Air supply during maintenance tasks
• Ideal for use on modular F.R.L. assemblies in automation racks
• Used with high-flow exhaust lines in pneumatic actuator systems
• Can be used for emergency depressurisation in production cells

What port configuration does it use for exhaust management?

It employs a three-port arrangement including an EXH port to route exhausted Air separately from the supply and outlet lines.

Which thread standard should installers expect for the ports?

The valve’s connection thread conforms to G thread specification suitable for compatible pneumatic fittings.

How does the locking mechanism enhance safety during servicing?

The handle requires a push then turn action before it reaches exhaust

when set to exhaust it accepts a padlock through locking holes to prevent reapplication of supply.

Are mounting and noise-reduction options available?

Optional accessories include a bracket assembly for secure mounting and a built-in silencer for the exhaust port to reduce discharge noise.

What material considerations affect chemical compatibility?

External structural components use flame-resistant resin and the main body is polybutylene terephthalate, informing selection where solvent or temperature exposure may be a concern.
