PVD

Description:
Compact positioner with closed loop and 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 600 cSt (mm²/s)

Control:
pneumatic: lubricated, unlubricated and 50 µm filtered compressed air, 4…10 bar, port G1/8
electrical: 0...10 V, optionally 4...20 mA, supply 24 V DC ± 10%, power consumption 150 mA / 3.6 W
feedback potentiometer 500 Ω, coupling socket 15 x 15 mm, 4 pin, Pg 7P, IP 65

Control_element:
2-port/2-way valve, NC (normally closed) as standard, optionally NO (normally open)
as option 3-port/2-way valve for mixing different media, with standard piston

Mounting_position: any
Protection_class: IP65
Linearity: < 2% FS
Repeatability: <0.5 FS
Failsafe: valve closes (NC) in the event of voltage failure, optionally outlet flow freezes (fail freeze)
Temperature_range: -10 °C to 60 °C / 14 °F to 140 °F
Control_valve_body: bronze, optionally stainless steel 316L
Proportional_valve_body: aluminium, PA and FV
Cone seal: PTFE
