2 port and 3 port motorised valves

Motorised plug & seat valves for control of heating & cooling systems. Valves and actuators are important products in heating, cooling and air-conditioning systems. They must operate reliably in rapidly changing conditions.

Empire Controls supply high-quality linear actuated valves. Our actuated valves are used in applications for heating systems, cooling and domestic hot water. The plug and seat valve have been developed based on market requirements to maximize on safe and accurate regulation for problem-free operation. The valves have a design which makes them self cleaning, resulting in long trouble free service life. 2 and 3 port control valves are available in a wide range. This range of valves are very cost effective due to low service requirements and a long service life.

Valves are also available with pressure-balanced plug, allowing them to be regulated with low thrust even with large pressure drops. The design of the valve plug prevents particles in the medium from getting caught. It also offers excellent resistance to erosion and corrosion damage. The plug is guided into the seat to prevent vibrations. The patented design also helps minimise flow noise. The valve’s flow characteristic has been modified by an equal percentage, providing good regulating control for the installation. This gives a high level of precision even with small flow rates. The motorised plug & seat valves can be used as a mixing valve or diverting valve.

The 3 port rotary shoe valve is used in heating and cooling systems to control and distribute the operating medium. The 3 port rotary shoe valve can be used as a mixing valve or diverting valve.

• The bsp female threaded valve is available DN20/50.
• The PN6 flanged valve is available DN20/150.

Examples of installations

All the examples of installations can be reversed.

The valve position plate is graduated on bothsides and shall at the installation be fitted in the correct position as shown in the instruction (see right) for installation. So it can be used as a mixing valve or diverting valve.

Empire Controls actuators for plug and seat valves are all self stroking (no need for limit switch adjustment) for easy on site commissioning. Available in either 230v Ac, 24v Ac, 24vDc & 24vDc 0-10v.

The 5Nm actuator is a compact design for operating rotary mixing valves and diverting valves DN15/50. The motor is reversible with fixed limit switches for an operating range of 90° and has manual override facility. Available in 230vAc or 24vAc.

The 15Nm actuators are for operating rotary mixing valves and diverting valves up to DN150 with high torque ratings. Power supply can be either 230V AC or 24V AC to suit all building management systems.
