pneumatic-hydraulic metal hard seal ball valve

QYIII series metal seal ball valve adopts a fixed ball structure, which conforms to relevant standards strictly regarding its design, material selection, manufacturing test, surface treatment and painting. There are multiple options for materials of its internal components, subject to application in working conditions. It is optional for full or reduced bore and also for many kinds of actuators, which is an ideal valve option for chemical engineering, petroleum refining, exploitation of natural gas and transportation systems. 

Pressure class: Class150-1,500
Diameter range: DN50~ 1000(4~36") 
Actuating mode: manual, electric, pneumatic, pneumatic-hydraulic, electric-hydraulic, etc.

Design standard
API6D pipeline valve   Fireproof test of APIFA valve API607 soft seal and fireproof test of 90° turn valve    Inspection and test of API598 valve   ANSIB14.34 flange, thread and welding end valve   JB/T 7745 pipeline ball valve

Technical characteristics of QYIII ball valve: 
● It adopts ANSYS finite element analysis software for 3D numerical simulation of its body as required by working conditions, meeting requirements for its strength and rigidity, thus being safer 
● The ball support is available for multiple designs as required by parameters of working conditions
● Available for providing the valve chamber purging structure design and the option of automatic pressure relief function of the valve middle chamber
● Double sliding bearing design both for protecting the packing box’s packing set and for reducing the valve’s operating torque 
● Its inlet and outlet are provided with double block and bleed function; light weight, compact structure and optional for either full or reduced bore
● The split seat design making its seal more reliable and maintenance more convenient; also available for providing an auxiliary sealant filler
● The enclosed seat structure is available for multiple designs subject to different working conditions
● The advanced mechanical equipment ensures the valve’s machining precision and assembling quality
