The 10P Seriessingle-seat control valve adopts the top guided unbalanced structure, featuredby high strength, heavy load, S type flow channel, low pressure drop loss, highflow coefficient wide adjustable range, high flow characteristic precision,etc. This kind of control valve is suitable for applications with relativelylow differential pressure with tight shut-off. It is suitable for controllingmedium flow or pressure. The cage adopts the press-in type seat design, whichsolves the problems of difficult disassembly and high leakage of the traditional thread screw-in type seat and prolongs the service life. The flow to opendesign is adopted, and the medium flow direction tends to the opening directionof the valve with good controllability of small opening and low flowcharacteristic distortion. Special cages with noise reduction and anti-cavitation functions can be offered according to the requirements in differentservice conditions.
