The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

Motorised Valves (18 products) Motorised heating valves are an electrically controlled valve used in central heating systems to control the flow of heated water in the home. Our range consists of both 22mm and 28mm diameters and 2 and 3 ports. They are available to click and collect in as little as a minute or have delivered for your convenience.
Jan 27, 2020 · When properly used, motorized valves present an elegant solution to the problems of controlling water or steam into a heating distribution system. Some common examples of these systems include: Steam Heating Distribution – In these applications, a motorized two-way valve can control the flow of steam from the boiler …
Inching valves. These valves offer more precise flow control compared to the on/off valves. Motorized actuator facilitates gradual opening and closing of the valve enabling some degree of control over the flow. Some examples include, reflux lines, boiler start up vent, boiler IBD valves, boiler main steam valves …
Kelden Feedwater Valve was developed nearly 32 years ago. After many years of searching for a modulating feedwater valve that would shut-off and not "leak thru", we decided to design our own. We currently have several hundred of these valves in high pressure steam applications all over the country and they simply work great.
The Motorized Ball Valvedelivers a torque of 150 in-lbs using a non-reversing motor, opening the valve in 5 seconds and minimizing pressure hammer. The motor is protected in a NEMA 4X enclosure and features an integral thermal overload protector with automatic reset. Repair kits are available as well.
The motorised valve can be used for control of both heating and hot water, and it works by controlling the flow of water from the heating boiler to other parts of the system. There are two types of motorised valve used in domestic heating systems: two port (also called zone valves), and three port (also called mid position valves).
Feb 10, 2019 · A motorised valve is a central heating system component which controls whether hot water from the boiler is used to heat the radiators, or the water in the hot water cylinder for the taps. It is usually found adjacent to the hot water cylinder, e.g., in the airing cupboard. As the name implies, it is electronically operated. Prolific manufacturers of motorised valves include Honeywell and Drayton.
Modulating Feedwater valves allow for constant incremental adjustments to feed water into your boiler. They come in all types from ball valves, to knife gates, to globe valves and operate off of many types of signals. Some typical applications are 0-135 ohm slide wires from a McDonnell and Miller 7b switch or a 4-20ma signal from a differential
Apr 01, 2021 · There are lots of choices for mixing assemblies. Two "classic" options are 3-way and 4-way motorized mixing valves. Both can provide the two critical functions when a conventional boiler is matched up with a low temperature distribution system: Preventing sustained flue gas condensation within the boiler.
