。 Q: multiple directional control valve assembly and pay attention to the things of project to try to answer: directional control multi-way valve is by means of relative motion between the valve core and valve body, to change a petition on the body of oil duct valve on-off relationship classes. 1. All parts should be carefully cleaned, use dry or dry skins. Multiple directional control valve is made up of two or more directional control valve as the main body of the valve. ( 2) Function will attempt to multiple directional control valve into the nominal pressure and flow pressure oil, under no leakage conditions, seizing the driving lever, should be able to get through no matter what a limit position, and semi-automatic fence-sitting position return. 2. Try: (after fit up 1) Tightly closed performance try: with pressure to zero. 2 - 0. 4 mpa compressed air and export through multiple directional control valves, directional control valve of the remaining use plug plug hole. If disclosure of leak, should be marked on a flat place to remember, before renovation. Accordance with the requirements of different office, also can be combined on the safety relief valve, check valve and fill valve is attached to valve. Multiple directional control valves appearance of leak phenomenon is not allowed. In the fifth through, should be resting on the limit position 3 min, and steering column should be able to semi-automatic fence-sitting position return. Then multiple directional control valves in 20 - in the oil 30 mm, open air valve, reversing Industrial Valves rod at two limit position. Try the function, all units should be driving lever to two limit position, each connected to four times. And other types of valve in Marine valve, multiple directional control valves have compact structure small pressure loss, close valve moving resistance small, there are a number of functions, the survival of the life long, make the advantages such as simple. ( 3) Accurate performance investigation: seizing at full load, reversing valve should be whether with minimum speed position, can load cylinder with the minimum speed. ( 4) External seizing tightly closed performance: will the outlet pressure is changed to 2. 5 - 3 mpa, change the inlet pressure to 20 mpa, the stem in 6 - each unit 10 s of time, through to the limit position 15 times, external oil leakage phenomenon is not allowed. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
