Overview

XSTOU FIG920 Double Eccentric Pneumatic Butterfly Valve Eccentric Clamp Butterfly Valve provides an economical and efficient solution for various applications that require airtight closure. This design utilizes an eccentric valve plate and a bias shaft to integrate 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.

Product Details

XSTOU FIG920 Double Eccentric Pneumatic Butterfly ValveThe eccentric butterfly valve provides an economical and efficient solution for various applications that require airtight closure. This design utilizes an eccentric valve plate and a bias shaft to integrate 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 FIG920 Double Eccentric Pneumatic Butterfly Valvefeature

Adopting ISO 5211 square driven full axis valve stem design

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 non pin shaft and the valve plate 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 to reduce valve torque

The alloy hardened valve plate sealing surface used for metal seats increases the sealing life

The integral valve plate stopper prevents the valve plate from exceeding its stroke

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

PTFE lined SS316 bearings support the valve stem and extend its service life

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