The Sun Hydraulics CNCCXZV (CNCCXZV) is a specialized hydraulic valve designed for precise fluid control in various hydraulic systems. This model is a fixed orifice, non-pressure compensated flow control valve equipped with a reverse flow check function. It operates by using a customer-specified orifice diameter, which must be determined upon ordering and is set at the factory to ensure accuracy. The orifice size directly influences the flow rate, allowing control in proportion to the square root of the pressure differential across ports 1 and 2. The CNCCXZV valve features Sun Hydraulics' floating style construction, which minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining. This design enhances the reliability and performance of the valve in demanding operational conditions. The valve fits within a T13A cavity and belongs to the Series 1 line, supporting up to 15 gallons per minute (60 liters per minute) with a maximum operating pressure of 5000 psi (350 bar). It accommodates an orifice range from .016 to .153 inches (0.4 to 3.9 mm). Additionally, this model is designed for interchangeability within its frame size for all 2-port flow control cartridges, although cartridge extension dimensions from the mounting surface may vary slightly. Each unit's specified orifice diameter is clearly stamped on one of the cartridge\u2019s hex faces for easy identification during maintenance or system checks. The CNCCXZV\u2019s robust construction and precise manufacturing make it suitable for applications requiring reliable non-compensating flow control where reverse flow checking is also necessary.

Description

This valve is a fixed orifice, non-pressure compensated flow control with a reverse flow check. The flow setting is specified by the user and is set at the factory.

Customer must specify the orifice diameter.
All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
These are essentially check valves with bypass orifices. The flow path matches Sun's flow controls and can be used in any flow control manifolds. Valves with the opposite direction of flow can be found under check valves with bypass orifices.
Because these valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.
The customer specified orifice diameter is stamped on one of the cartridge's hex faces.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.

Show FAQ

What happens if I block the control flow (priority) port?	All flow is blocked, hence the term priority. The priority flow has to be satisfied.
What happens if I block the bypass port on a priority flow control?	The valve acts as a 2 port restrictive flow control.
What is the compensating pressure of Sun's flow controls?	The spring force in our flow controls equates to about 100 psi (7 bar). This is high enough to give the valves acceptable capacity (not really) and not too high for proper circuit operation. 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.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
What is the pressure drop through a flow control?	In a meter-in flow control circuit if the pump is set at 3000 psi and the load is 2000 psi the drop through the flow control is 1000 psi. In a meter-out circuit with the load at 2000 psi the drop through the flow control is 2000 psi.
How accurate are Sun's flow controls?	We claim +/- 10%. We set to +/- 5% in production testing to allow for differences in customers' conditions. If you want accuracy, stay in the bottom 2/3rds of the range. Our 12 gpm (45 L/min.) flow controls are quite flat at 9 gpm (34 L/min.) and dead flat below 6 gpm (23 L/min.), until you get to the bottom of the range. Below about .25 gpm (1 L/min.), spool leakage and orifice conditions start to limit accuracy.
I have a heat problem, will Sun's priority flow control help?	I am afraid not. Unless you are overflowing your current valve and correctly size ours, you are not likely to notice any improvement. Priority flow controls are not efficient devices. They are an easy way to get more than 1 source of oil from 1 pump but they can generate a lot of heat. Try to size your actuators so the pressures are similar on both the priority and the bypass circuits. If you can't do that, try to have the lower flow leg be the lower pressure. The pump pressure is determined by whichever leg is higher and if there is flow that is taking a pressure drop that is not doing work it is creating heat.
