DUAL PLATE
برای قیمت تماس بگیریدDual plate check valves are used to protect installations against backflow. They are entirely operated by reaction of flow and they do not require any external actuation.
The main advantages of dual plate check valves vs swing check valves are: lightweight, short dimensions. Moreover, line shock is reduced or eliminated. Due to the reduced face to face this check valve can be mounted vertically or horizontally thanks to a return spring.
Dual check valve can be designed as wafer, lug or flanged type.
ECCENTRIC TYPE
برای قیمت تماس بگیریدEccentric Type Butterfly Valve
The eccentric type butterfly valve has three categories and they are – single-offset, double-offset and triple-offset. The availability of single-offset valves is rare in the marketplace whereas double-offset and triple-offset are the commonly used ones.
Oftentimes, these two sub-type of eccentric butterfly valves are also referred to as high-performance butterfly valves. The double-offset valve comprises two offset. The first one is located slightly behind the disc and it helps in making the valve have a consistent sealing surface on the disc.
Whereas the second offset is situated on the slightly right side of the disc’s center. This offset works to prevent the valve from coming in contact with the seat when it is completely open. This arrangement of the seating design helps in less friction and contributes towards prolonged service.
The triple-offset valve on the other hand has three offset and the first two offset does the same job as double-offset one. Only the third and additional offset of this valve has a conical shaped seating which is made to match with the disc that is also fabricated to match with the seating.
This seating arrangement helps in preventing friction or rubbing completely while it’s opening or closing. It also enables the valve to have a bubble-tight performance in the high-pressure application and have a much longer lifespan in comparison to double-offset butterfly valves.
