The VHS series provides a convenient means of isolating supplied pressure in a pneumatic system and exhausting downstream pressure for maintenance purposes.  The units can be locked in the exhaust position and can be an integral part of an energy isolation system.  Air flow direction is easily identified by handle orientation and labelling.  

• 3 port pressure relief valve
• Accessory for AC-D series
• Lockable for energy isolation
• Single action operation, simply turn
• Resin or metal handle construction
• Port sizes (inches): 1/8, 1/4, 3/8, 1/2, 3/4, 1

This product will end production in March 2025. -- Please select the VHS*-D series for new applications

• Manually operated valve that can be used to prevent accidents caused by residual pressure in pneumatic lines
• Possible to verify the supply and exhaust status of air flow at a glance
• When in the exhaust position, the valve can be padlock secured. This prevents accidental start-ups while personnel are cleaning or servicing equipment.
• Stainless steel body with aluminum or stainless steel handle
• Validated according to ISO13849
