Hydraulic control valve

Hydraulic control valve as used in industrial applications are built in several pressure ranges. The majority of present applications are in the range of 0 to 1500 lb per sq in., but the trend is toward higher pressures. Various types of valves are used in hydraulic systems to control or regulate the flow medium. Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves. Common types of hydraulic valves include angle, ball, block and bleed, check, control, cartridge, directional, drain, needle, poppet, pressure relief, safety, shut off, solenoid, spool, and stack mounted valves. In their unpowered state, hydraulic valves can be normally open (open center) or normally closed (closed center). Hydraulic control valves with a tandem center connect the pressure and tank ports, but block the service ports to allow system unloading and isolation of the service lines. Devices with a float center allow the supply to be shut off and enable the load to move to other services.

200X Pressure Reducing Valve

200X pressure reducing valve

Product Simple Specification

The valve maintains a preset downstream pressure, regardless of upstream pressure or flow fluctuation. The main valve is controlled by a pilot valve, which makes the main valve modulating to maintain the downstream pressure.

Product Specification

The 200X pressure reducing valve is an intelligent valve that uses the self energy of the medium to regulate and control the pressure in pipes. The 200X pressure reducing valve can be used in domestic water supply,fire fighting water supply and other industrial water supply systems. The outlet pressure of the main valve can be regulated through the adjustment of the pressure reducing valve; the outlet pressure does not vary along with the inlet pressure and inlet flow. Accordingly, the outlet pressure can be safely and reliably maintained at a preset value and the preset value can be adjusted according to actual needs to obtain your pressure reducing goal. This valve is precise in pressure reduction, stable in performance, safe, reliable, easy, convenient to install and adjust and offers a long service life.Pressure Rating: PN10. PN16.

Solenoid valve

1) Prevent the valve from being strongly striken in the process of installation and shipment, otherwise it may influence its normal performance.
2) Before installation, the user must check it flatly on the test clamps with some prepressing. It is not allowed to be freely-flip. This assures that magnetic material won’t be damaged by colliding, otherwise it will influence the magnetic force.
3) Clean the impurity such as aluminum or oil left on the inner wall of the stove and the surface of it.
4) Keep the good connection of the solenoid and thermocouple. Prevent the safety protection device from operating abnormally because of too big contact resistance.5) The warehouse of solenoid valves must be dry and ventilated and strictly prohibit extrusion.

CHECK AND ADJUST VALVE CLEARANCE

Too little valve clearance throws its out of time. It open too early and close too late. This causes the valves to overheat due to hot combustion gases rushing past valves when out of time. Overheating lengthens valve stems which prevents proper seating of them. Them seat so briefly or poorly that normal heat transfer into the cooling system does not have time to take place, causing burned them and low power.Too much of them clearance causes a lag in valve timing causing engine valve train imbalance. The fuel-air mixture enters the cylinders late during intake stroke. The exhaust valve closes early and prevents waste gases from being completely removed from cylinders. Also, the they lose with a great deal of impact, which may crack or break the it and scuff the camshaft and followers.NOTE: It clearance should be checked with engine cold.
