SIEMENS 110498 1/2" Valve Size .63 Flow Rate CV(Kvs) Brass End Connection NPT-NPT HVAC Control

1/2" NPT. N.C. VALVE BODY .63CV

The 1/2" NPT. N.C. VALVE BODY .63CV is a double outlet valve with one inlet and one outlet port in an NPT type body, designed to be installed on heat transfer equipment. The body and bonnet are constructed of brass. A self-lubricating, PTFE liner provides leakage-free movement of the internal ball and the seat closure around the ball is controlled by a helical spring which also prevents the seat from uncovering

Siemens 1/2" N.C. Brass Control Valve with .63 CV, Pressure Relief, and Roughing End Connections has a 1/2"NPT male N.C. threaded connection and pressure relief that is designed to provide precise control of flow and temperature range following process or load demands for optimized system performance. It features a normally closed operation and non-rising stem to accommodate low inlet pressures which fall within the most common fluid restriction ranges for general industrial applications such as heating

1/2" N.C. Brass End Connection Valve Body with hex adjustment cap includes built-in check valve and has .63 CV (Check valve flow coefficient) of permeability. Flow is measured at .5’ W.C. outlet pressure and 20°F vent temperature.

Our 1/2'' Valve Body is constructed of brass and is sold packaged individually. It is designed to meet the performance demands of a variety of HVAC applications where reliable performance and high flow are required. This product is intended for commercial applications only.

The Siemens 110498 air purge valve is designed with a fully welded brass body, and features an NPT NPT male inlet connection. It has a flow rate of .63 CFM to provide continuous air purging. This 1/2" push-to-connect purge valve has been tested for use with gas, liquid, and steam applications, and meets the Underwriters Laboratories (UL) safety requirement for category IV division 2 locations. It can withstand pressure of up to 300 PS

PEERLESS VICR20LF1-10 is a 1/2" brass twist on flow control valve with durable brass body and washer-less disk design, for globe type piping applications. The valve hub is used to install and remove the cartridge. The position of handle will determine direction of flow. The stainless steel needle valve needle and spring are accessible from outside of the body.

For commercial applications where added control is needed industry standard valve products work well, while providing ease of operation for the technician. Working valves can often be reused if they are carefully inspected, cleaned and serviced. Valve bodies vary in design, but the basic operational principles remain the same: prevent flow with a disk or poppet device, create a vacuum to pull flow, or use an upstream pressure differential to push a piston into a packed column, increasing resistance to flow. Additionally, these products connect to
