Product Description
Functioning as the pneumatic equivalent of an auxiliary relay in an electrical system, it amplifies, branches or isolates pilot air signals in compressed-air circuits. With metric Rc (PT) 1/8 ports, an operating pressure range of 0 to 1.0 MPa and ambient tolerance from -5 to 60 deg C (no freezing), it suits a wide range of factory automation and pneumatic control applications. The SMC VR4152-F01A-1 is a pneumatic relay valve (transmitter-relay) from the VR4151/4152 series, designed to perform fixed operational sequences based on pneumatic signals received from a mechanical valve.
Basic Product Information
- Metric Rc (PT) 1/8 connection ports in a side-ported design
- Operating pressure 0 to 1.0 MPa; pilot pressure 0.15 to 1.0 MPa
- Lubrication-free (no oil required) operation
- Ambient and fluid temperature range -5 to 60 deg C (no freezing)
- Double-pilot transmitter-relay valve for fixed pneumatic sequencing

Frequently Asked Questions
What is the difference between the VR4151 and VR4152 relay valves?
The VR4151 is a single-pilot relay valve, while the VR4152 is a double-pilot version. Both perform relay functions in pneumatic systems based on received pilot signals.
What fluid and pressure range does the VR4152-F01A-1 support?
It is designed for compressed air with an operating pressure of 0 to 1.0 MPa and a pilot pressure of 0.15 to 1.0 MPa.
Does this valve require lubrication?
No. The VR4152-F01A-1 is a lubrication-free (no-oil) design, though turbine oil Class 1 ISO VG32 may be used if preferred.
What port size and connection type does it use?
It uses metric Rc (PT) 1/8 ports in a side-ported, sub-plate-mounted configuration.
