On deleting one or both the signals, the piston is reset. The valve does not switch if the input signals are not received within 0.5 sec. To restart, both the signals must be deleted first. Application SZ: For machines and devices that must be turned on using both hands (e.g. presses). Cylinders up to Ø 160 can be operated directly using valve SZ 14510 or SZS 14510. Function SZS: In addition to the two signal inlets Z 1 and Z 2, this two hand control block also has the signal connec- tion Y. Signal to Y switches the two hand control block like a normal 5/2-way valve. Application SZS: 1. For machines and equipment that need to be turned on using both hands, however shortly before stroke-end switch to "detend". Both manual buttons can already be released before the stroke-end. Detend is turned on by the limit switch (signal to Y), and released by a time valve or pressure switch. 2. For machines and equipment that optionally can be turned on with both hands or one hand, or by means of a foot switch. 0,5s 2 4 1 12/2 12/1 3 5 0,5s 2 4 14 1 12/2 12/1 3 5 0,5s 2 1 12/2 12/1 3 type SZ 18 310 standard design precision design type SZ 14 510 type SZS 14 510 Materials: Body: Aluminium anodised, internal parts: Aluminium, brass and stainless steel, seal: Plastic/NBR Temperature range: -10°C to max. +70°C Construction type and function: Ÿ Pilot operated piston valve with low actuating force. If not activated, a small air quantity of approx. 2.5 l/min escapes from the pilot part. Ÿ Pressure connection always at 1, outlet at 2, venting through a borehole on the surface of the valve. Ÿ The surface within the four bases of the valve may not be covered. Ÿ At actuation the valve switches from throughway 1 to 2. Application: Ÿ For turning on machines and equipment of all types, especially in pairs as two-hand indenting. With the small switch force of the Servo principle, a fatigue proof working is guaranteed in the continuous operation. The bracket around the button protects against accidental actuation. 3/2-way servo key return switches with "low actuating force" Type Thread Flow Basic setting ST 18 310 G 1 / 8 “ 3 mm 220 l/min. 3 - 10 bar 3.5 N Closed 3 1 2 Signal interrupters Type Thread Precision design SU 25 310 M 5 Approx. 0.3 sec. 3 - 10 bar SU 18 310 G 1 / 8 “ Approx. 0.3 sec. 3 - 10 bar Standard design SU 18 310 B G 1 / 8 “ 0 - 10 sec. 2 - 10 bar (adjustable) Materials: Body: Aluminium anodised, internal parts: Aluminium and stainless steel (standard design: brass), seals: Plastic and NBR Temperature range: -10°C to max. +70°C (standard design: -10°C to max. +60°C) Media: Oiled and unoiled compressed air Function: This valve intercepts a continuous signal, so that the continuous signal at the input connection 1 generates only a short pulse at the outlet 2. A signal received at 1 flows to the outlet 2. After the pulse, the pressure generated in the valve switches over the piston. Connection 1 is blocked, outlet 2 vents after 3. 2 1 3 precision design standard design Push-in fittings Ø 3 - 32 mm from page 24 Nominal width Operating pressure Operating pressure Pulse length Switch force at 6 bar Nominal width Operating pressure Control pressure* Control conn. 14 - 12 T1 R1 R2 R3 cyli n der 1 cyli n der 2 APH Techniek BV - Wateringen - T +31 (0)174 219 200 - sales@aphtechniek.nl - www.aphtechniek.nl 433
