B220B+LF120-S is a two-position valve that directs the fluid flow to either Zone 1 or Zone 2. It has a separate auxiliary switch for each zone to regulate pressure. The regular Open and Close Settings provide switching valves for the two zones. The third Setting, the Auxiliary Switch, can be used in conjunction with the other two Settings (Open/Close) to allow interaction between both top port and bottom ports of B220B+LF120-S.

Auxiliary switch with a spg return, suitable for use w/ a ceiling mounted control panel (code CAU, CCU or CKU) and w/ an air actuated valve assembly (code B220B+LF).

The B220B+LF120-S is a 2 position wiring scuttle valve with Auxiliary Switch and fill port return. It is UL/CULus listed and protected against water intrusion in accordance with NEC, Article 410. Fill Port Return/Preconnect: This valve has a function that allows for a ballcock to be used for fill port return. The valve opens on the first cycle and does not close when a tank empties since the fill port has been returned. This is far superior than the old way of having constant fill pressure because now one can actually monitor their tank level.

Meets City of Los Angeles 2009 Green Building Regulations for minimum LEED credits – Certified to meet LEED "Platinum" zero energy and water use requirements when combined with a high efficiency heat pump system. Available with panel mount Auxiliary switch or field installed Auxiliary switch (B-220B+LF120-S; 120V; 24v/12v)

The sleek B220B+LF120-S is ideal for industries ranging from light industrial to retail settings. It offers a high flow (24 Cv), uniform temperature and precise modulating control. This commercial heating valve's switch is an Add On included in the package. The rotary selector dial lets you select: Hot, On, and Auxiliary.

The B-Series 3/4" CCV, 2-way solenoid valve is used to control water flow in 1/2" or 3/4" pipe. The valve has a rechargeable diaphragm allows for a long service life and is resistant to vibration, high pressure and resistance to dry out when valves are left open. The maximum working temperature is 120 degrees centigrade / 250 degrees Fahrenheit and the maximum working pressure (pressure at which failure due to internal leakage begins)is 16 bar / 240 psi. The two way valve can be placed between the main and final branch, or at any

Plug-in Type Switches are ideal for commercial uses. They control two circuits and offer four connection terminals for external wiring harness.
