Piston valve PVE1 series

pneumatically-operatedfor controlmixing

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 - 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 Linearity/Hysteresis: < 2% FS Repeatability: < 1.0% FS Failsafe: valve closes (NC) in the event of voltage failure, optionally outlet fail freeze feature Control_valve_body: bronze, optionally SST 316L Cone_seal: PTFE Proportional_valve_body: aluminium, PA and FV
