pressure compensated flow valve
Item #100493440. This flow control valve is composed of a Pressure Compensator valve block and a Variable Orifice block. Flow control valves are constructed of brass and steel materials. As a function of a setpoint value, the flow controller swiftly adjusts the desired flow rate. A pressure compensator is a device built into some pumps for the purpose of automatically reducing (or stopping) pump flow if system pressure sensed on the pump outlet port, should rise above a pre-set desired maximum pressure (sometimes called the "firing" pressure). The spring force in our flow controls equates to about 100 psi (7 bar). Any remaining flow is bypassed to the "EF" or excess flow port. PC2H Pressure Compensated Flow Control Valve. FCHH & NVHH for 10,000 PSI. The variable orifice determines the flow cross section. The pressure reducing valve and the smothering of this valve are placed in series with each other. Pressure-compensated flow control valves compensate for these fluctuations by maintaining the hydraulic motor's rpm at a constant level.

It CAN be used as a priority type flow regulator, or a restrictive type, 2-way, flow regulator when the bypass line (port 2) is blocked. Any upstream or discharge pressure variations are automatically compensated by a built-in membrane operated valve to ensure a steady, constant flow. Flow control pressure compensated valves. Applications In-line pressure-compensated flow control valve. Three basic types of cartridges are available; restrictive-type, priority-type, and divider/combiner type.

Four rotations of hand knob to facilitate the setting with ease. Compact Hydraulics. The compensator orifice modulates its opening to maintain a constant pressure drop across the control orifice. In the research, the flow-control valve with controllable pressure compensation capability (FVCP) was designed firstly and theoretically analyzed. First - the simple purpose of a pump is to provide the flow needed to transmit power from a prime mover to a hydraulic actuator. We made up some prototypes, put them . List Price: $390.00 ex.

Pressure-compensated flow control valves are used with actuators that must move at a constant rate, regardless of pressure. The two-way pressure-compensated flow control valve is also called a series valve. An adjustable, pressure compensated, flow control valve. Flow rate of hydraulic oil flowing through an orifice will be dependent over the following two factors as mentioned below. Whereas the non-pressure compensation is operated by manual throttling of oil passage. The control valves do not require any electrical power source, since the desired flow rate is manually set via the needle valve. Application. Compare. 100 psi (7 bar) is the spring force; at the upper end of the flow control's range, the drop through the valve will be as high as 250 psi (17 bar) before it starts modulating.

By rotating the handle, the flow out the "CF," or controlled flow port, can be varied from approximately 0 to the maximum controlled flow allowed. Then the sub-model model of PPRV and. This valve has a fairly simple design, and it produces a simple effect,. Flow up to 90 lpm (24 gpm) and pressure up to 420 bar (6000 psi); excess flow is diverted once the priority flow requirement is met. LunchBox Sessions 79.9K subscribers We'll spend the next three videos looking at the Pressure Compensated Flow Control. Valves can be ordered with or without adjustable internal reliefs. This unit is a screw in, cartridge type, adjustable, poppet type, hydraulic flow control valve with or without free reverse flow check. Flow Control Valves. They generate a set constant flow rate, largely independently of the load. While proving out the FC1AH & NV2AH ultimate quality SS valves announced last year, our engineers noted that with a little tuning, the design would be a natural for 10,000 PSI extreme duty service. Parker offers a wide range of pressure compensated flow controls for applications that demand constant flow with varying loads and pressures; handling pressures as high as 420 bar (6000 psi) and flows to 56 lpm (15 gpm) in a single common cavity.
