Hydraulic valves are used to contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems such as oil reservoirs. Angle, ball, block and bleed, directional, drain, check, cartridge, poppet, pressure relief, shut-off, spool, stack mounted and control are all types of valves used in systems that are hydraulic. Control valves are used to modify flow and form the major valves used in oil reservoirs. Hydraulic control valves like all other hydraulic valves can be normally open or closed in an unpowered state.
There are various types of hydraulic control valves that regulate or control the flow medium in a hydraulic system. Basically valves, including hydraulic control valves, are used to
" Control direction of flow
" Control pressure of flow media
" Control the blocking and stopping of flow
" Control flow quantity
A complex hydraulic system such as that used in oil reservoirs require a number of hydraulic control valves to maintain the flow throughout the system. Examples of hydraulic control valves include relief valve, master control valve, sequence valve, reducing valve, check valve and flow control valve. In a simple oil circuit system the first hydraulic control valve that is encountered is the relief valve followed by a second valve which is almost always the master control valve. In more complex systems, the oil flows through a number of hydraulic control valves before it finally returns to the reservoir.
Hydraulic control valves are used in many industrial applications and need to be built in several pressure ranges from 0 to 1500 Ib per square inch. Other specifications for hydraulic control valves include valve size, ports, flow coefficient, media temperature and connection type. The valve sizes in hydraulic control valves are measured in inches and the media temperature is expressed in Fahrenheit degrees. Both double-port and multi-port hydraulic control valves are available and come with several types of connections. At Hanbay (www.hanbayinc.com) you can find a wide range of valves for a number of applications including hydraulic control valves. Established in Montreal, Canada since 1986, Hanbay specializes in custom actuators and valves.
The actuators in hydraulic machines continuously move to and fro making the direction of fluid flow an important aspect when operating any system that is hydraulic. Control valves, specifically direction control valves are used to achieve the desired direction of fluid flow in the circuit. Pressure hydraulic control valves have been designed to increase or decrease the pressure of the fluid in mechanical or hydraulic systems. Because actuators need to be altered according to the operational requirements it is important to use hydraulic control valves that can modify the flow of fluid.
Whether you are looking for hydraulic control valves or electric valve actuators, Hanbay stocks a wide range of solutions to fluid pressure and gas pressure control. All their products undergo reliability testing before being released into the market, guaranteeing you peace of mind when you buy hydraulic control valves from Hanbay. Industries rely on a reputable supplier for hydraulic control valves and other accessories used in pressure control; Hanbay incorporates quality checks on every item after every manufacturing process, from parts acceptance to the finished product.
