5/2-way limit valve, roller actuation, G 1/4", 700 l/min, stainless steel 1.4436, FKM seal

Drying ovens, welding fixtures and washing systems often run at temperatures well above what a standard pneumatic valve tolerates. This 5/2-way limit valve is therefore machined from 1.4436 stainless steel and sealed with FKM, covering a temperature range of -20 to +180 °C. Roller actuation requires a force of 89 N at 10 bar and drives double-acting cylinders directly. The flow rate is 700 l/min through G 1/4" ports, with two further G 1/4" threads taking the exhaust air. Two nuts for panel mounting are supplied, sized for a 24 mm hole in sheet metal of up to 5 mm.

Advantages

• Body, spool and roller in 1.4436 stainless steel resist cleaning agents and condensate.
• Temperature range of -20 to +180 °C thanks to FKM seals.
• Flow rate of 700 l/min for driving double-acting cylinders directly.
• Operating pressure from -0.95 to 12 bar, so vacuum duty is possible as well.
• Actuating force of 89 N at 10 bar gives a clear figure for designing the cam track.
• Two panel mounting nuts included, for a 24 mm hole and a maximum sheet thickness of 5 mm.

Applications

• End position sensing on fixtures inside drying and curing ovens up to +180 °C.
• Cleaning and washing lines where aluminium housings would corrode.
• Hot runner and forming tools with direct control of double-acting cylinders.
• Operator panels using panel mounting in sheet metal of up to 5 mm.
• Vacuum circuits down to -0.95 bar on handling equipment.
