2 -' '7 \ Bottom Entry Stem As safety is of primary concern, Watts utilizes a bottom loaded stem in all ball valves. he stem is retained by a machined shoulder in the body of the valve that mates up to a shoulder on the stem. Stem Sealing Method A critical component of any valve is its stem sealing capability. Unlike many of our competitors, at Watts we exclusively employ a "packing gland" style stem seal design. he Watts stem seal provides a compression force independent of stem rotation. Either a yoke or threaded body style stem seal retainer is used, depending upon the valve size and model. hreaded Seat Retainer he method by which a unibody, flanged-end ball valve retains the seat/ball assembly is critical to its performance and to the safety of those who install and operate these valves. Watts utilizes a safe, responsible and accurate method to accomplish this function - by threading the seat retainer into the valve. he size and number of threads that firmly hold the seat retainer to the valve body have been designed to comply with the respective ANSI Class rating of the valve. he outside diameter of the seat retainer is inside of the gasket surface providing additional sealing of line fluid if internal gaskets are damage by temperature or fire conditions (sizes W'- 6"). And, the Watts Series 1500/2500 is rated forfullbi-directionalshutoff, as wellas "dead-end" service. Ball Construction EveryWatts industrialvalve is of a solid ball construction, which provides structural integrity and reduced flow turbulence not available when "hollow" or formed balls are used. A hole is drilled into the stem slot of each ball to equalize pressure between the body cavity and the flow stream. his feature prevents seat damage due to thermal cycling by allowing media trapped within the. body cavity (between the outside of the ball and the inside of the body) to expand and re-enter the general flow stream through that drilled hole when the valve is in the open position. UnisealM Seat Materials Watts Regulator introduces a new, state-of-the-art seating material.unisealmis unfilledpfe,providingthe benefit of very low operating torque and almost universal chemical compatibility,yet has the strength of filledpfe,resulting in higher pressure/temperature ratings. UnisealMgains its strength from a modifiedmolecular grain that significantly reduces PFE'stendency to cold flow.unisealmmaintains this strength at higher temperatures, and performs well at saturated'steam conditions up to 150 psig.
