Pneumatic high-performance double eccentric butterfly valve

XSTOU X-D-092-F05-F07-SQ17 pneumatic high-performance double eccentric butterfly valve, FIG910S high-performance pneumatic butterfly valve design adopts eccentric valve plate and offset shaft, combining flexible lip sealing system into a lightweight and compact valve body. As a result, in many cases, valves can replace globe valves and gate valves, but with simpler operation, longer duration, and lower cost.

XSTOU X-D-092-F05-F07-SQ17Pneumatic high-performance double eccentric butterfly valve， The FIG910S high-performance pneumatic butterfly valve is designed with an eccentric valve plate and offset shaft, combining a flexible lip sealing system into a lightweight and compact valve body. As a result, in many cases, valves can replace globe valves and gate valves, but with simpler operation, longer duration, and lower cost. The significant performance of this valve makes it widely used in airport refueling, hydrocarbon treatment, HVAC, air treatment, chemical treatment, gas purification, steam and vacuum services, drinking water, powder and pulp processing, and many other applications. The clamp design makes the valve easy to connect between flanges and saves pipeline length.

XSTOU X-D-092-F05-F07-SQ17Pneumatic high-performance double eccentric butterfly valve， Structural characteristics of FIG910S high-performance pneumatic butterfly valve

Full axis valve stem design with ISO 5211 square drive

ISO 5211 integral flange

After the execution device is installed in place, the sealing cover can be easily adjusted

The disc spring on the gland nut provides reliable sealing force between the shaft and the seal

The packing gland evenly compresses the packing and prevents the valve shaft from protruding

Multiple rows of RPTFE or graphite V-shaped sealing rings ensure self sealing of the valve shaft

Extend the height of the upper flange to facilitate pipeline insulation

Self reinforcing valve seat can extend service life and reduce maintenance costs. The connection between the valve body and the valve plate without a pin makes the valve easy to replace components and reliable even in corrosive conditions

The valve seat pressure plate supports the valve seat and allows for easy replacement

Double offset valve plate for reducing valve torque

Alloy hardened valve plate sealing surface for metal seat increases sealing life

Integral valve plate stopper prevents valve plate from overtravel

Soft valve seat, fireproof valve seat and metal valve seat can be replaced with each other

PTFE lined SS316 bearing supports valve stem and extends service life

Thrust ring is used for anti slip and anti-static purposes

Connect standard clip on FIG910S, ear support FIG910U

Specification size 2 '-24'

Work pressure Class150, Class300

Flange standards ASME B16.5 Class150, Class300; EN1092 PN16, PN25, PN40
