Who makes Erie valves?
Schneider Electric (ERIE) Zone Valves ½” to 1 ¼” Sweat, Flare, Threaded.
What is a modulating valve?
A modulating control valve is an automated valve that is used to control the amount of flow in a system or process. They go beyond simple shutoff or isolation (on/off) and actually allow precise control of the flow rate.
What does an Erie pop top actuator do?
Erie™ PopTop™ Series valve bodies and actuators provide easy installation for a variety of heating and cooling applica- tions. The valve’s actuator can be installed after the valve body has been installed onto the fan coil, baseboard or air handler. VS Series valves are available for low pressure steam applications.
What is an Erie valve?
The Erie™ Modulating PopTop™ Series valve actuator assem- blies are designed for closed hydronic heating and cooling systems. The Modulating PopTop is used to control fluid flow in fan coil units, VAV reheat, unit ventilators, AHUs and radiant applications.
Are zone valves universal?
Zone valves are normally made to attach to certain thread sizes, which have become increasingly universal as time has gone on, but it’s still a good idea to pay attention to any specifications written up by the manufacturer.
What is 2 way modulating valve?
A 2-way valve is any type of valve with two ports: an inlet and an outlet port, typically labeled “A” and “AB” respectively. 2-way valves are used in many applications, from basic on/off to more complex variable flow applications with pumps and VFDs.
How does a modulating float valve work?
They are ideal for balancing the inflow and outflow demand into the reservoir and maintaining level at the designated maximum. The valve closes drip-tight at the maximum level and modulates to maintain the tank level. The float pilot is remotely installed at the high level in the reservoir tank.
How do I install Erie pop top actuator?
Installing Erie VT-VS PopTop Series Two Position Spring Return Valves
Where is the zone valve located?
A zone valve can be located right after the boiler and circulator (hot side), or at the end of the zone circuit (cold side). If able, it is recommended to locate the valve on the cold side as it will be less damaging to the valve and improve its life-time.
What is the difference between a 2 way and 3 way valve?
What is the difference between a 2 way and 3 way valve? A 2-way valve is any type of valve with two ports: an inlet and an outlet port. A 3-way valve has three ports within the valve body which are used as inlet, outlet, and exhaust.
How does a 3 way modulating valve work?
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.
What are the different types of float valves?
Float Valves
- Brass and Bronze Float Valves. EZ Flow Valves.
- Large Valves. High Capacity Valves.
- Straight Pipe Valves. Simple Valves.
How does automatic water level control valve work?
Automatic water level controllers switch the motor on whenever the water level drops below a certain level and shuts the motor off when the water rises well above a fixed level.
Can I manually open a zone valve?

When would you use a 3 way valve?
The ability to mix fluids from more than one inlet makes 3 way valves ideal for heating and cooling various media such as water, oils, and chemicals. These valves are also commonly used as bypass valves in primary and secondary loop applications.
What is the difference between 2 way and 3 way valves?
What function differentiates a 2 way valve from a 3 way valve?
3 way valves contain the same components as 2 way valves. What differentiates it from the 2 way valve is the use of an additional port.
What is the difference between a Type 1 and Type 2 ball valve?
On a Part 1 or ‘Portsmouth’ valve, the outlet is on the underside of the valve. However, on a Part 2 or ‘diaphragm’ valve, the outlet is on the top. Water is directed down into the cistern via a small plastic spout which screws onto the valve body.
How much pressure can a float valve hold?
When measuring pressure for ball float valves in in piping, it is common to use the pounds per square inch measurement. Thus, the ball float valves used in the GFTS family of gravity-fed tank safety showers are suitable for a psi range of roughly, 29.0 to 145.0 psi.

How do I know if my zone valve is bad?
Heat not working / Zone valve replacement – YouTube
Why do zone valves fail?
The zone valve opens and closes according to the temperature in the room as determined by the thermostat and your settings. Sometimes the zone valve will fail to operate properly. This can be caused by a malfunctioning part on the valve itself or by a faulty thermostat or a faulty connection between the two.
What happens if a zone valve is installed backwards?
Reply: problems caused by zone valves installed backwards include banging pipes and reduced valve life. A slow-closing type zone valve may cause banging heating pipes if installed backwards.
