S6056/57 series fan coil unit actuators and valves

S6056/57 series fan coil unit actuators and valvesUsed together, it has the characteristics of small size, flexible installation, and easy maintenance. The S6057 series fan coil valve belongs to the normally closed type valve, which can be divided into three types according to the diameter: DN15, DN20, and DN25. This valve also has two ways and three ways. In terms of materials, the valve body is made of forged brass, and the valve stem and spring are made of stainless steel.

S6056/57 series fan coil unit actuators and valvesOperation method

When the valve stem moves downward under the drive of the actuator, the valve core overcomes the resistance of the stainless steel spring, leaves the valve seat, and opens the normally closed valve.

When the power is turned on, the actuator motor pushes the component, overcomes the resistance of the return spring, and pushes the valve stem downwards.

When the power is cut off, the return spring overcomes the medium pressure and pushes the valve stem to the closed position.

install

When assembling the fan coil actuator with the S6057 series fan coil valve, the following requirements must be followed:

The direction of water flow must be the same as the arrow on the valve body, so that the valve core can block the water flow.

Valves and actuators must be installed within a 90 ° vertical range, without dripping water, and easy to install electrically.

Valves must be connected to water pipes using appropriate equipment.

Do not use the actuator as a lever to move the valve body.

The actuator should not use insulation materials, and there should be at least 20mm of space above it for assembly and disassembly.

Warning

▲ When operating manually, do not apply too much force or speed too quickly to avoid damaging the actuator.

▲ The water quality must meet the requirements of VDI-2035 standard or air conditioning operation system, and other media must be approved by Solon Company before use.

During maintenance, ensure that the power supply to the actuator has been cut off to avoid equipment damage, personal injury, or electric shock. Do not touch or disassemble the circuit when the power is turned on.
