Conforming to OSHA Standard: Pressure Relief 3 Port Valve with Locking Holes VHS
-
?Compliant with OSHA Standards (Occupational Safety and Health
Administration Department of Labor)
?This manually operated valve can be used to prevent accidents caused by
residual pressure in pneumatic lines.
?The supply and exhaust status of air flow can be confirmed at a glance.
?When in the exhaust position, the valve may be padlock secured. This can
prevent accidental start-ups while personnel are cleaning or servicing
equipment.
?Push the knob and then turn. This 2-step action can prevent
malfunctions.
? The VHS series will be discontinued in March 2025.
Please select the VHS-D series.
