Check valve, pilot operated
Design:
Complete with four fastening bolts M4 x 25 - 8.8. Spring-loaded ball seat valve for plate assembly, leak oil free. Components made of steel. The connection channels must be self-produced using connection plates. Sealing is with O-rings. Nomenclature of the connection ducts: A = consumer, B = pump side, Z = control, L = leak oil (relief of the vacuum piston chamber)
Application:
For unhindered flow in one direction and blocked flow in the other direction. The blocked direction can be controlled via a control connection. The valve is used for the leak oil-free pressure maintenance on hydraulic consumers in combination with leak oil-containing directional spool valves or leak oil-containing media penetrations.
Note:
Max. perm. pressure at connections A, B = 700 bar, Z = 250 bar. Connection L must be positioned without pressure relative to tank. The minimum pressure for keeping the connection open is calculated from the formula pst = a x Δp + b x pB + c! Coefficients for valve 6916-08-10: a = 0.235 / b =0.03 / c = 4.8! Δp = Flow resistance and pB = pressure at connection B, see diagrams.
