Hand & mechanical directional valves

Transcription

1 Table E5-3/E Hand & mechanical directional valves ISO 44 sizes 6,, 6 and 25 H- Hand & mechanical operated directional valves are spool type, three or four way, two or three position valves, available with following actuator types: - mechanical actuator: general purpose execution for connection to customer device for the valve s remote operation - hand-lever - cam (only for H and K). Valve sizes and max flow: H- = size 6, flow up to 5 l/min K- () = size, flow up to l/min K-2 = size, flow up to 4 l/min P-2 = size 6, flow up to 3 l/min P-4 = size 25, flow up to 7 l/min P-2 body spool mechanical actuator without lever lever cam 5 H-2 Max pressure: 35 bar for H-, P-2, P-4 35 bar for K-* MOEL OE H- 3 / / ** / * irectional control valve, size: H- = 6 K- = P-2 = 6 P-4 = 25 Type of actuator: = mechanical, without lever = hand-lever 2 = cam (only for H- and K-) Valve configuration, see sections and = free, without springs = spring centered, without detent 2 = retun to internal position 3 = return to external position 4 = 3 position, with detent 5 = 2 external positions, with detent 6 = centre plus external positions, with detent 7 = return to external position from the centre position 8 = return to the centre position from the external position Spool type, see section Series number Seals material: - = NR PE = FKM Options: / = actuator device mounted on side of port Lever position to be specified for H-, H- and K-, K- with configuration 6, 7, 8, see section for hydraulic connections: /I = in rest position the lever is inclined towards the valve body * * /E= in rest position the lever is inclined in opposite side * * Only for K-: /Y= external drain Only for H- hand-lever valves: / = short hand - lever and reducend actuation force 2 RNGE OF VLVE S MOELS VLVE TYPE H- H- H-2 K- K- K-2 P-2 P-2 P-4 P-4 SIZE VLVE ONFIGURTION E5
