ValveMounted Dial w/ RemoteSensorSide Mount AngleFPT x MPTUnion Tailpiece Valve mounted operators provide fastacting modulating control of the spacetemperature through a patented vaporcharge, ensuring the highest level ofcomfort control. Standard valve mounted operators areequipped with a “snap-action” mechanismthat allows for easy installation and removalwithout the use of tools. Optional anti-theftprotection clips are available. Tamper resistant versions of the valvemounted operators are available todiscourage unauthorized adjustment,vandalism and theft. Conforms to ASHRAE / ANSI Standard102-1983. RA 2000 valves are fitted with a packinggland assembly that is replaceable while thesystem is in operation. The packing gland isfitted with a grease cup to ensure the o-ringpacking is lubricated for life. Sturdy EPDM rubber valve disc provides apositive seal against the valve seat atdifferential pressures of up to 15 PSI in hotwater heating systems, while 15psig for lowpressure steam systems. Plastic cap supplied to protect the valvepushpin can provide manual control ofthe valve during installation. If manualoperation is required, a separate hand knobis available as an accessory. Valves remain normally open with nooperator mounted. Conforms to ASHRAE / ANSI Standard102-1983.Separate RemoteMounted Dial and SensorValve Features:Straight FPT x MPTUnion Tailpiecesystems.

Range: 45-86 F (7-30 C)Comfort Control:Control of the space temperature at acomfortable level is easily accomplishedby adjusting the dial clockwise or counterclockwise. The dial has a numbered scaleof 1 to 5 corresponding to temperatures ofapproximately 57 F to 79 F (14 C to 26 C).Indicator TabShould the space be unoccupied for anextended period, the dial can be set to the “ *”symbol for freeze protection (50 F or 9 C) tosave energy.Indicated temperatures are approximate.Adjust the dial to the desired setting.Design and Function:The RA 2000 thermostatic operator consistsof a saturated vapor charged bellows and asetting dial. The dial is set to the position equalto the desired temperature. When the ambienttemperature lowers, the pressure from thebellows will reduce, allowing the valve to open.A rise of temperature increases the pressurein the bellows closing the valve. The balancedpressures between the adjustment spring andthe bellows ensure a smooth and modulatingoperation of the valve.

Forbest comfort control and long life,valves should be selected to providedesign flow at a 4 F P-deviation.Hydronic Hot WaterApplicationsExample:Flow Required:0.65 US GPMPipe Size: 1 2”Solution:Draw a line from 0.65 USgpmuntil it intersects with thedashed line for the 1 2” valve.Draw a vertical line down tofind the additional systempressure drop due to the valvewill be 0.6 psi.Low PressureSteam Applications:The shaded area representsdifferential pressure above thoserecommended for quiet operation.The maximum differential pressureratings indicate the maximumpressure at which valves regulatesatisfactorily. In order to preventnoise, pumps that provide onlythe required pressure should berecommended. Experience showsthat in most systems a differentialpressure of0.5 - 2.5 psi across the valve issufficient to provide the requiredflow.Step-by-step selection techniqueSolution:From the table below a 3/4” valve will provide28MBH at a 4 F P-deviation at a pressure dropof 3psi. If the system pressure is 3psi or greater a3/4” valve can be used.1. Before selecting valves, consider P-deviation.2. Check that system pressure is below 15psig.3.
