The Lug type of the Butterfly Valve Flanged configuration is like a 3-piece ball valve in that one end of the line can be produced off without having a results on the contradicting side. This can be executed by utilizing strung supplements, ribs, alongside two arrangements of hauls (screws) that don’t use nuts since every rib includes its own fasteners. 

It’s additionally imperative to take note of that you don’t have to close down the whole framework so as to clean, review, repair, or supplant a carry butterfly valve (you would need to with a wafer margarine valve).

Description

Butterfly Valve-FlangedButterfly Valve-Flanged 

 

Offered in Butterfly Valve-flanged, these valves are accessible with Ductile Iron, Carbon Steel or 316 Grade Stainless steel. These valves are in stock with both BUNA-N and EPDM liners.  Viton and PTFE liners are accessible upon demand and comes default with the Basic Manual multi position lever.

The new outlines joins a one-piece stem with an imperative new element.  The plate is suggested to fit the processed square stem with enables the circle to coast, giving significantly enhance torque valves.

It is likewise accessible with lever administrators and worm adapt administrators and highlight bubble tight close off.  The carry arrangement is reasonable for deadlock benefit. All Butterfly Valves can be changed with augmentations, geared hand wheel and different actuators.

 

STEM:

 

Precision double “D” disc to stem connection drives the disc without the need of screws or pins.

 

SEAT:

 

SRS’s bonded seat design lowers torque and provides complete isolation of flowing media from the body.  In addition, the seat also features a molded O-ring which eliminates the use of flange gaskets.

 

STEM RETAINING ASSEMBLY:

 

The stem is retained in the body by means of a unique Stainless Steel  retaining ring, a thrust washer and two C-rings, manufactured from brass as standard, stainless steel upon request.  Also, the retaining ring may be easily removed with a standard hand tool.  Finally, the stem retaining assembly prevents unintentional removal of the stem during field service.

 

STEM BUSHING: 

 

Non-corrosive, heavy duty acetal bushing absorbs actuator side thrusts.

 

STEM SEAL: 

 

Double “U” cup seal design is self-adjusting, gives positive sealing in both directions, and prevents external substances from entering the stem bore.

 

EXTENDED NECK: 

 

Extended neck length allows for 2″ of piping insulation and is easily accessible for mounting actuators.

 

PRIMARY & SECONDARY SEALS: 

 

These seals prevent line media from coming in contact with the stem or body.  Also, the primary seal is an interference fit of the molded seat flat with the disc hub. 

In addition, the Secondary Seal is the stem diameter that is greater than the diameter of the seat stem hole.

 

DISC: 

 

Spherically machined and hand polished to provide a bubble-tight shutoff, minimum torque, and longer seat life.
