Product Description
Product Description
Pilot Operated Control Valves provide unmatched tight shut-off performance for high-temperature applications(Working temperature >230ºC). In high temperature and high-pressure conditions, even if the seat has a small leaking can also cause serious erosion of the plug and seat. Therefore the Control valve has good sealing performance is very important in these cases. The general method to improve the sealing performance is to increase the actuator size, However, the Pilot Operated Control Valves improve the sealing performance by the pressure difference between the inlet and outlet of the valve, this structure can reduce the size of the actuator, and improve the sealing performance.
Features:
1. Fluid flow is from up to down, pilot balanced Cage Guided Control Valve has a separate pressure-balanced pilot plug compared to the regular cage control valve.
2. The main plug is closed tightly by the output force of the actuator and the unbalanced force from fluid pressure difference while the valve is closed. The pilot plug is closed tightly by the output force from the actuator and the spring reaction force.
3. The flow capacity in the channel of the pilot plug and seat should be bigger than the flow capacity in the guided ring and the gap between plug and cage, otherwise, the pressure balance cannot be established and this would lead to valve closure.
4. The opening of the pilot plug is controlled within the range of 10% of the valve opening, otherwise the range of the small flow valve can not be adjusted.
5. Small size, compact structure, good sealing performance
6. High ability of cut-off, long service life. This series can be used for evacuation and shut-off, especially on occasions with high temperature, high pressure, and large valve size.
Benefits:
Cavitation can happen even if the valve seat has a small leakage in high temperature and high-pressure difference occasions, and this would lead to valve trim damage with long-term erosion to the plug and seat. So it is vital to keep complete sealing without any leakage for the valve on these occasions. Normally, increasing the output force would promote the sealing level. For a pilot-balanced cage-guided Single Seated Control Valve, the actuator size can be reduced and sealing performance can be promoted by using the unbalanced force from the flow pressure difference. And this makes the product even more competitive.
