All data are considered to be unbinding reference values. We accept no liability for data selection that is not confirmed in writing. Pressure data refer, if not otherwise indicated, to liquids of Group II at +20°C. 7 Time valves/logic valves 3/2-way time valves 20 to 300 seconds Type Thread VZ 25 310/300 M 5 2 - 6 bar 20 - 300 sec. Materials: Plastic Temperature range: 0°C to max. +60°C Media: Oil-free compressed air Function: If pressure is applied to connection 1, the time set starts to run. After the time set has expired, input 1 is swit- ched to outlet 2. The resetting is carried out by interrupting the supply air at input 1. Time adjustment: Continuously adjusted using the rotary knob 2 t 1 3 5/2-way time valves (standard design) 1 to 10 seconds Type Thread Flow Function VZ 18 512 B G 1 / 8 “ 530 l/min. 3 - 10 bar 1 - 10 sec.

Backwash filter delayed Materials: Body: Aluminium anodised, internal parts: Aluminium, brass and stainless steel, seals: NBR Temperature range: -10°C to max. +60°C Media: Oiled and unoiled filtered compressed air Pressure input: Connection 1 Function: Type VZ 15 812 B (reaction: delayed, backwash filter: immediately): A continuous signal at connection X trig- gers the switching of the valve according to the time set. If no signal is at connection X, then the valve switches back to the initial position. Type VZ 18 513 B (reaction: immediate, backwash filter: delayed): A continuous signal at the connection X triggers an immediate switching of the valve. The valve switches back to the initial position according to the time set. If no signal is at connection X, then the valve also switches back to the initial position. 4 2 12 135 14 R X R 4 2 12 135 14 X type VZ 18 512 B type VZ 18 513 B 3/2-way time valves (precision design) 0.25 to 20 seconds Type Thread Flow VZ 25 310 M 5 3.2 mm 160 l/min. 3 - 10 bar 0.25 - 5 sec.

G 1 / 8 “ Materials: Body: Aluminium anodised, internal parts: Aluminium, brass and stainless steel, seals: Plastic and NBR Temperature range: -10°C to max. +70°C Media: Oiled and unoiled filtered compressed air Pressure input: Connection P (1) (closed basic setting) or connection R (3) (open basic setting) Function: This valve switches on after a delay. It can be used when closed in the idle position or when open in the idle position. Pressure connection at P (1) shows the function "Closed in idle position", while the pressure connection at R (3) shows the function "Open in idle position". In the idle position, the flow from R (3) to A (2), connection P (1) is blocked. After the set time elapses, a signal received at Z (12) switches the valve to flow from P (1) to A (2), R (3) is blocked. On deleting these signals, a spring immediately resets the piston. A connection of the signal conductor Z (12) to P (1) or R (3) is possible. It must be noted here that the signal conductor to the valve connection P (1) or R (3) is not longer than the signal conductor to Z (12). 3 1 2 12 Warning! An AND-element does not replace a two hand control block! (see page 433). AND valves Type Thread Flow Precision design AN 25 M 5 3.2 mm 160 l/min. AN 18 G 1 / 8 “ 4.0 mm 280 l/min. Standard design AN 25 B M 5 2.5 mm 100 l/min. AN 18 B G 1 / 8 “ 2.5 mm 100 l/min. Materials: Body: Aluminium anodised, internal parts: Aluminium, brass and stainless steel, seals: Plastic and NBR Temperature range: -10°C to max. +70°C (standard design: max. +60°C) Media: Oiled and unoiled filtered compressed air Operating pressure: -0.95 to 10 bar (standard design: 2 to 10 bar) Function: At outlet A a signal appears only if a signal exists on both inlets at the same time. For different pressures, the lowest pressure will reach outlet A. The AND member has no separate venting as a passive element. After deleting one or both input signals, ventilation oc- curs via the upstream signal members. Y X A precision design standard design Suitable for vacuum Time range Control conn.
