ZXS pneumatic diaphragm angle-shape single-seated regulating valve:
1) It uses top guiding structure, supported by multiple spring actuators. The valve body applies cross structure. It is of compact configuration, light weight, motion agility, and large valve capacity exact flow characteristics and self-cleaning. This type of valve can be used in occasions of small allowable leakage, high-viscosity, and the fluid containing suspended solids or granular materials, for it can avoid coke, interception.
2) The nominal through diameter rating DN (mm) is 20~200 (3/4"~8") and the nominal pressure rating PN consists of PN(MPa)1.6\4.0\6.4\10.0; (AMSE Class: 150lb/ 300lb/ 600lb /900lb) etc. The applicable temperature is -196~+560celsius, the leakage class: IV/V/VI. Flow characteristic: Linear, equal percent. The product also includes a variety of specifications.
Types of ZXSD
*ZXSO has standard type and heat dispersing type. (pic 1, 2)
* ZXSV The bellows type and single-seated type. (pic3)
* ZXSD low temperature type. (pic4)
* ZXSQ regulate and cut-off valve whose soft sealing type structure up to class VI leakage standards (micro-bubble level) (pic 5)
* ZXSJ-type jacket and insulation belt with stainless steel insulation jacket for easy to crystallize after cooling fluid \ solidification caused by blockage occasions (pic 6)
* Spool \ seat are made of build-up satellite, suitable for high temperature \ deep cold and other harsh conditions.
