heat insulation jacket single-seat control valve adopts the top guided unbalanced structure, featured by high strength, heavy load, S type flow channel, low pressure drop loss, high flow coefficient, wide adjustable range, high flow characteristic precision, etc.
The cage adopts the press-in type seat design, which solves the problems of difficult disassembly and high leakage of the traditional thread screw-in type seat and prolongs the service life. The flow to open design is adopted, and the medium flow direction tends to the opening direction of the valve with good controllability of small opening and low flow characteristic distortion. Special cages with noise reduction and anti-cavitation functions can be offered according to the requirements in different service conditions. valves are of heat insulation jacket type, mainly used in applications where media such as paraffin may easily coagulate at normal temperature. Fill the heat insulation jacket with steam to heat the medium and maintain its flow.
