HCP-10001 Sleeve-Guided Bellows Single-Seated Control Valve
The valve body has a compact structure, an S-shaped fluid channel, and a guide vane to improve the balanced flow of fluid around the sleeve, resulting in low pressure drop loss, large flow rate, wide adjustable range, and high flow characteristic accuracy, which meets the IEC60534-2-1-2011 standard. The regulating valve has good dynamic stability, low noise and small cavitation corrosion. The upper valve cover adopts a bellows sealing structure, which is suitable for extremely toxic, flammable, explosive, volatile and rare precious metal media. Alternatively, the valve can also be used in vacuum applications.

Features & Benefits
”Bellows+packing“ double seal
The valve stem shaft seal adopts a double-safety structure with a metal bellows as the main seal and packing as a backup seal—suitable for toxic (chlorine, phosgene, etc.), volatile, valuable, and highly corrosive media, meeting environmental protection requirements for fugitive emission control.
Balanced cage type single seat structure
The sleeve single-seat structure with a balanced sealing ring not only retains the advantages of small opening and closing force of the pressure balancing valve core, large allowable pressure difference, and the ability to be equipped with a small actuator, but also raises the leakage level to the level of a single-seat valve.
The sleeve single-seat structure with a balanced sealing ring not only retains the advantages of small opening and closing force of the pressure balancing valve core, large allowable pressure difference, and the ability to be equipped with a small actuator, but also raises the leakage level to the level of a single-seat valve.
The valve core is fully guided by a sleeve, has a large guide area, strong lateral resistance, small opening without vibration or whistling, good dynamic stability, low noise, and small cavitation corrosion.
S-shaped flow channel + guide vane
The valve body flow channel is S-shaped, and guide vanes are arranged around the sleeve to improve fluid balance flow: low pressure drop loss, large flow capacity, wide adjustable range, and high flow characteristic accuracy (complies with IEC 60534 standard).
Easy to maintain
Sleeve-type internal components can be quickly replaced online, resulting in short maintenance time for the halt and saving manpower.
