KEYCENTRIC PLUG VALVES - Homestead Valve

1 Valve SIZING & RATINGSS izes - 4 KEYCENTRIC Plug ValveSeries 300 Eccentric Valvesare availablein 9 sizes from - 4 . This Valve isideal for many applications includingHVAC systems, natural gas andcombined hot and chilled water Size, Light Weight Smallbody size makes this Valve ideal forapplications where space is of this compact line areshown on the back page. Light weightminimizes the need for pipe are shown in the Valve Balancing and Shutofffor Air Conditioning Application The optional Adjustable Memory Stopprovides both balancing and shutoff inone Valve . With the memory stop lockedin place, except when equipped with anattached lever actuator, the Valve can beclosed and then reopened to the samebalanced position.

Theresilient plug seal is pressed firmly intothe seat for dead-tight plug and seat design assurelasting shutoff because the plugcontinues to move into the seat untilfirm contact and seal is the plug closes,it moves towardthe seat without scraping the seat orbody walls so there is no plug bindingor wear.

DOUBLE-SEAL FOR TIGHT SHUTOFF AND SAFETYA resilient seal molded into a groove in the plug faceassures dead-tight sufoff on liquids and gasses withoutthe use of sealing lubricants. When the plug is closed,the resilient seal is compressed against the seat. Themetal on the plug face also makes contact with the metalseat to provide a second seal for safety.
