DG17 are lever operated valves used for applications requiring two and four-way directional operation. The two-way valves are available in both spring offset and no-spring detented versions. The four-way valves are offered in spring offset, spring centered and no-spring detented versions.
Max. pressure P, A & B ports:
Max. pressure T port : 70 bar (1000 psi)
Mounting Interface: ISO 4401-05 CETOP 5 NFPA D05
Handle shift force:
Operating temperature: 20° to 50° C (70° to 120° F)
Fluids & seals: BUNA-N seals are standard and are compatible with water-inoil emulsions, high water based fluids, and petroleum oil. “F3” (Viton) seals are compatible with phosphate esters, and “F6” seals are for water glycol. Maximum operating pressure for high water based fluids is 69 bar (1000 psi).
Shifting action: Spring offset valves are spring positioned unless lever is actuated. Spring centered valves return the spool to center position when the lever or knob control is released. Nospring detented valves will remain in the last position attained provided there is no severe shock, vibration or unusual pressure transients.
Mounting position: No-spring detented valves must be installed with the longitudinal axis horizontal for good machine reliability. The mounting position of spring-offset, and spring centered models is unrestricted.
Installation data: On two-way valves “T” is the drain connection and must be piped directly to tank through a surge-free line so there will be no back pressure at this port. NNote: Any sliding spool valve, if held for long periods of time, may stick and not spring return due to fluid residue formation and therefore, should be cycled periodically to prevent this from happening.
