aerospace climate control electromechanical filtration fluid & gas handling hydraulics pneumatics process control sealing & shielding Parker Angle Seat Valves PA Series, 2/2 Way, NC or NO 3/8" to 2 1/2" BSP, 16 Bar

Parker Angle Seat Valves Introduction An angle seat valve is actuated by a pneumatically driven piston and is capable to handle slurry solutions with particles or corrosive solutions at high temperature up to 180°C and operating pressure up to 16 Bar. Benefits • Compact design, high flow rates • Visual position indicator • For temperatures from -10°C to 180°C • Working pressures up to 16 Bar • Dampened closing anti-water hammer design (fluid under seat) • Stainless Steel actuator housing for exceptional durability in steam and aggressive applications • Valves meeting Pressure Equipment Directive...

RED Position indicator on all models Housing is 304 Stainless Steel standard, or optional Aluminum Brass Piston Piston ring FKM Pilot port available in BSP Spring loading on packing glands for tight sealing Dual stem bearings for "true" guidance and superior life Chevron Seals - PTFE Precision rollerburnished 316 Stainless Steel stem for long life Body 304 Stainless Steel or 316L Stainless Steel for excellent corrosive protection PTFE seal provides resistance to aggressive fluids, high temperature and tight sealing Water-hammer free flow under seat
