Smc Pneumatics NVZM450-N01-34R Mechanically Operated Valve

Product Description

The SMC PNEUMATICS NVZM450-N01-34R is a mechanically operated pneumatic directional control valve featuring a twist selector actuator. It provides manual control of compressed air flow in pneumatic circuits without requiring electrical actuation. The valve is rated at a Cv of 0.550 and offers a 4-position, 5-port configuration, making it well suited for applications that require multiple discrete flow paths. The 1/8 inch NPT inlet threads directly into standard pneumatic manifolds or plumbing. The red actuator body aids in visual identification on multi-valve assemblies. Licensed pneumatic system technicians and industrial maintenance professionals are the primary installers of this component.

This valve is used in industrial and commercial pneumatic control systems where manual, tool-free directional switching is needed. Typical applications include machine tool actuation, cylinder sequencing, and process control panels. The twist selector design allows the operator to rotate and lock the actuator into one of four positions, directing airflow accordingly. It is appropriate for use in light manufacturing, automation, and MRO maintenance scenarios where a compact, low-flow directional valve is specified.

Key Features

• Twist selector actuator enables manual 4-position directional control without tools
• 5-port valve configuration supports multiple circuit paths from a single body
• Cv rating of 0.550 for controlled low-flow pneumatic circuits
• 1/8 inch NPT inlet for direct integration with standard pneumatic plumbing
• Red actuator body for quick visual identification on panel or manifold assemblies

Compatibility

Designed as an OEM-style replacement or direct-install option for pneumatic directional control applications requiring a 5-port, 4-position mechanically operated valve with a 1/8 inch NPT inlet.

Installation Notes

Installation should be performed by a qualified pneumatic technician or industrial maintenance professional. Depressurize the system and exhaust all stored air from the circuit before removing or installing any valve component. Apply appropriate thread sealant to NPT connections and verify all port assignments match the circuit diagram before pressurizing. Follow applicable facility safety lockout/tagout procedures throughout the service process.
