Where would you install a triple duty valve?
Model 3DV Triple Duty Valves must be installed on the discharge side of the system or zone pump with the valve facing the direction of flow as indicated by the arrow on the valve body.
What are the 3 functions of a triple duty valve?
The Bell & Gossett Triple Duty® Valve is a combination valve that provides all of the functions normally required on the discharge side of hydronic pump systems. The design combines three valves into one: a calibrated balance valve, a spring loaded check valve, and an isolation/shut-off valve.
What are the functions of a triple duty valve select all that apply?
As you can plainly see, the utilization of the Triple Duty valve is the most economical way to perform the functions of a balance/throttling, shut-off, and check valve, as well as being the smallest physical choice, thereby saving valuable space in the mechanical room.
What is 3way valve?
3 Way Valve is a constant flow rate valve used for either mixing or diverting application. In these valves, the total flow rate remains constant. These valves can be normally closed, normally open or universal. 3 way valves provide a convenient, economical means of diverting flow from one pipeline to another.
What’s a 3 way valve?
A three-way ball valve has three ports or openings that are connected to piping or tubing for gas or fluid flow (media) to pass through. These ports are usually described as one inlet and two outlet ports or one outlet and two inlet ports depending upon the flow direction through the valve.
What is the difference between two way valve and three way valve?
2 way and 3 way valve classifications are commonly used in industrial applications. These valves are defined by the number of ports they use. 2 way valves, as their name suggests, consist of two ports: an inlet port “A” and an outlet port “AB.” On the other hand, 3 way valves consist of three ports: “A,” “B,” and “AB”.
What is a 3 way valve used for?
A 3-way control valve shuts off water flow in one pipe while opening water flow in another pipe. In a modulating or 3-point floating application the valve can also mix water from two different pipes into one pipe or divert water from one pipe into two different pipes.
Why choose triple duty® valves?
The combination of multiple valves helps save space and reduces installation time and money. All Triple Duty® Valves features a calibrated nameplate designed to allow you to accurately balance your system and throttle excess flow. Model 3DV valves utilize a calibrated ball valve design that also provides complete shut-off.
What is a triple duty hydronic pump?
The Bell & Gossett Triple Duty® Valve is a combination valve that provides all of the functions normally required on the discharge side of hydronic pump systems. The design combines three valves into one: a calibrated balance valve, a spring loaded check valve, and an isolation/shut-off valve.
Why Bell & Gossett triple duty® valve?
The Bell & Gossett Triple Duty® Valve saves space and reduces first cost and installation costs by combining all the functions normally required on the discharge side of most HVAC systems into one convenient design. It features a calibrated balance valve, non-slam check valve, and positive shut-off valve all rolled into one.
What are 3D and 3DS valves made of?
Model 3D (angle pattern) and 3DS (straight pattern) valves are manufactured with iron bodies, brass discs with EPDM seats, and stainless steel springs. They are available in sizes 2” – 16”, feature flanged and grooved end connections, and are suitable for either 175 psi (flanged) or 300 psi (grooved) pressure and 250°F.
