113 Piloted Non-Return Valves Function Fittings 01 // Fittings Level 3 reduit / EN_Level 4 sans numero Component Materials Technical Characteristics Piloted non-return valves are designed to protect installations: if the compressed air supply is removed, they lock the air supply to the cylinder, thus maintaining it in position. Ø metric: 6 to 12 mm Advantages • Mounted in pairs on a cylinder • 3 functions in 1 compact product: - piloted non-return valve - flow control regulator - manual exhaust • Vent saves time on restart after maintenance operations • Compatible Fluids: compressed air • Working Pressure: 1 to 10 bar • Working Temperature: -5°C to +60°C • Cracking Pressure: 0.3 bar Silicone-free Operation Gripping ring: stainless steel Seals: NBR Flow control regulator body: technical polymer Body: nickel-plated brass Venting button: nickel-plated brass Piston: nickel-plated brass Valve poppet: nickel-plated brass, technical polymer Locking nut: nickel-plated brass Adjustment screw: nickel-plated brass P R R V P P Pilot signal (P) Regulation of cylinder rod speed (R) Drop/removal of pilot pressure (P) = cylinder rod locked Venting (V) returns the cylinder rod to the to start position, emptying the pressure chamber through the flow regulator (R) and pilot line (P) Normal Operation Emergency Stop or Pressure Drop Venting Operation Connecting tee Control valve To the control valve Non-return valves closed Non-return valves open Non-return valves open Model Pilot and depilot threshold 2 bar 4 bar 6 bar 8 bar 10 bar G1/8 Pilot Pressure 1.2 1.72 2.44 2.96 3.56 Depilot Pressure 0.56 0.96 1.12 1.76 2.12 G1/4 Pilot Pressure 0.92 1.52 2.12 2.68 3.28 Depilot Pressure 0.64 1.16 1.68 2.16 2.64 G3/8 Pilot Pressure 1.12 1.84 2.56 3.32 4.08 Depilot Pressure 0.64 1.04 1.44 1.84 2.36 G1/2 Pilot Pressure 1.04 1.60 2.12 2.76 3.88 Depilot Pressure 0.76 1.28 1.76 2.20 2.72 Maximum Flow at 6 bar (Nl/min) 7894 06 10 7894 06 13 7894 08 10 7894 08 13 7894 08 17 7894 10 17 7894 10 21 7894 12 21 Direction of Adjustment 250 475 240 585 875 940 1535 1560 Return 365 620 355 815 1085 1205 1860 1940 Regulations • RoHS • REACH • PED Piloted Non-Return Valves
