Detailed Product Description

  It is a pressure balanced regulating valve, using cage-type cage guide, single-seated sealing structure, equipped with multiple spring agencies, streamlined S flow channel, choose import MA43 series of balanced sealing ring. As a whole it has a high stabilization, large allowable pressure differential, precise flow characteristics of precision, low noise characteristics, especially for small allowable leakage but large pressure differential occasion.

Main technical parameters:

·         1)nominal size: DN20-200mm )

·         2)nominal pressurePNMPa1.6\4.0\6.4\10.0(ASME Class     150/300/400/600 )                                                  

·         3)leakage class: IV/ V/ VI

·         4)flow Characteristics: Equal percentage, linear

·         5)temperature range: -196~+560

 

Types of ZXG:

*ZXGO Standard type, the operating Temperature -20 ~ +200, leakage grade IV .(PIC 1)

 

* ZXGG Heat dispersing type, the valve covers additional heat radiator which can be used for medium of temperature -60 ~ +450 occasions (PIC 2)

 

* ZXGV The bellows type, which guarantee the sealing of the movement of the stem to form a complete seal environment, blocking external fluid leakage (PIC 3)

 

* ZXGD low-temperature type, the valve using long-necked tube and bellow sealed structure which can be used for cryogenic -196 occasions (PIC 4)

 

* ZXGQ regulate and cut-off valve whose soft sealing type structure up to class VI leakage standards (micro-bubble level) (PIC 5)

 

 Spool \ seat are made of build-up Stellite-alloy, suitable for high temperature \ deep cold and other harsh conditions.
