Elevator Control Valves EN ISO 9001 The BLAIN EV program includes the widest range of options offered to the elevator industry for high performance passenger service. Easy to install, EV‘s are smooth, reliable and precise in operation throughout extreme load and temperature variations. Description Available port sizes are ¾", 1½", 2" and 2½" pipe threads, depending on flow. EV‘s start on less than minimum load and can be used for across the line or wye-delta starting. According to customers‘ information, valves are factory adjusted ready for operation and very simple to readjust if so desired. The patented up levelling system combined with compensated pilot control ensure stability of elevator operation and accuracy of stopping independent of wide temperature variations. EV valves include the following features essential to efficient installation and trouble free service: Simple Responsive Adjustment Temperature and Pressure Compensation Solenoid with Connecting Cables Pressure Gauge and Shut Off Cock Self Closing Manual Lowering Technical Data: Self Cleaning Pilot Line Filters Self Cleaning Main Line Filter (Z-T) Built-in Turbulence Suppressors 70 HRc Rockwell Hardened Bore Surfaces 100% Continuous Duty Solenoids 1½" & 2" EV Flow Range: l/min 10-125 (2-33 US gpm) 30-800 (8-211 US gpm) 500-1530 (132-404 US gpm) Pressure Range (valve): bar 8-100 (116-1450 psi) 8-100 (116-1450 psi) 8-68 (116-986 psi) Press.

Warning: Only qualified personnel should adjust or service valves. Unauthorised manipulation may result in injury, loss of life or damage to equipment. Prior to servicing internal parts, ensure that the electrical power is switched off, cylinder line is closed and residual pressure in the valve is reduced to zero. Adjustments UP Valves are already adjusted and tested. Check electrical operation before changing valve settings. Test that the correct solenoid is energised, by removing nut and raising solenoid slighty to feel pull. Nominal Settings: Adjustments 1 & 4 approx. level with flange...
