1 3/2- and 2/2-way cartridge valve type BVE fr any flw directin, zer leakage, all prts pressure resistant Flw Q max = 300 lpm Perm. pressure p max = 500 bar Additinal valves with same functin: Type EM, EMP D 7490/1 Type BVG 1, BVP 1 D 7765 (Q max = 20 lpm, p max = 400 bar) Type NBVP 16 D 7765 N (Q max = 20 lpm, p max = 400 bar) Type BVG 3, BVP 3 D 7400 (Q max = 60 lpm, p max = 315 bar) Cartridge valve Versin with cnnectin blck 1. General The slenid actuated 2/2- and 3/2-way directinal valves type BVE are designed as seated cne valves. All prts are equally pressure resistant due t the internal pressure cmpensatin. The valve returns autmatically int its idle psitin because f the spring return, while nt actuated. The valves are cmpletely made f steel, with all functinal internal cmpnents being hardened, permanently lubed by the hydraulic fluid. As these valves are designed as cartridge valve, installatin is mst simple and quick. The slenid cil can be easily replaced, withut pening the hydraulic system e.g. when a different vltage is required. There are als individual cnnectin blcks available fr these valve, enabling direct pipe cnnectin. 2.

13 D 7921 page Appendix 5.1 Manual emergency actuatin Actuatin aid (d nt use any sharp-edged parts) The valve may be actuated by pressing dwn the brass blt visible frm abve by means f a steel pin r a screw driver etc. Attentin: Any pressure at B puts a lad n the brass pin, which results in a pressure dependent cunter frce. The pin diameter with type BVE 1 and 3 is #3 mm, i.e. 100 bar & 70 N; whereas it is #4 mm with type BVE 5, i.e. 100 bar & 125 N! 5.2 Actuatin slenid ptin B used as actuatin lck (see table 3a) This actuatin lck may be used as safety device e.g. during maintenance wrks r initial peratin / set-up peratin. Standard peratin - Slenid (cil) is munted - The lcking nut fixes the cil at the armature tube - Actuatin is unlcked - Valve can be actuated via the slenid Maintenance wrks / initial peratin - Slenid (cil) is nt munted - The lcking nut is nly lightly screwed nt the armature tube - Valve is fixed in wrking state Standard peratin Maintenance wrks / initial peratin Lcking nut
