PVE

Compact positioner with analogue control. Compressed air for
remote control necessary. The stroke is made proportional to the
flow through the parabolic contour of the piston. The valve shuts
tight and is of anti-water hammer design.

Media: compressed air, vacuum up to 10-2 mbar or liquids up to
viscosity of max. 600 CST (mm2/s)

Control:

1. pneumatic
- lubricated and unlubricated and 50 µm filtered compressed air
- 4...8 bar
- port G1/8

2. electrical
- 0-10 V, optionally 4-20 mA, supply 24 V DC ± 10%,
- power consumption 150 mA/3.6 W
- analog position feedback signal 0-10 V / 4-20 mA (after automatic balance)

Control element:
2-port/2-way valve, NC (normally closed) as standard,
as option 3-port/2-way valve for mixing different media,
with standard piston

Electrical connection: cable gland, optionally M12

Mounting position: any
Protection Class: IP 66
Linearity/Hysteresis: < 2% FS
Repeatability: < 1.0% FS
Failsafe: valve closes (NC) in the event of voltage failure, optionally outlet fail freeze feature

Temperature range:
Ambiance: 0 °C to 50 °C / 32 °F to 122 °F
Medium: -10 °C to 180 °C / 14 °F to 356 °F

Control valve body: bronze, optionally SST 316L
Cone seal: PTFE
Proportional valve body: aluminium, PA and FV
