TVJ 3100B (C) Series Valve

TVJ 3100B (C) Series Valve

The TVJ 3100B and TVJ 3100C series cast copper valves are equipped with the TQM3100A electronic drive control unit to regulate the flow of cold water and hot water. Widely used in central air conditioning, heating, water treatment, industrial processing industries and other series of liquid control.

Installation and maintenance

The lower part of the stem is the valve closing direction

Before the valve is closed, the pipe should be cleaned, and there should be no scale, metal sheets and other debris left during welding.

When the pipe is connected to the valve, it must be concentric and free from vibration. The direction of the water flow should be consistent with the one indicated on the valve body.

When the drive is mounted vertically on the valve body, avoid installing the drive under the valve body, leaving enough space for routine maintenance (such as removing the drive)

The power supply must be cut or isolated when the valve is maintained. The water system should be free of pressure.

TFV2016 Split Electric Valve

The TFV2016 series split electric valve is used to control the central air conditioning system, the opening and closing of the heating system piping, to achieve the purpose of controlling the indoor temperature. The control valve is driven by a one-way hysteresis synchronous motor. The spring is reset. When the valve is not working, it is in the normally closed state. When it is necessary to work, the temperature control valve provides a valve opening signal, so that the electric valve is connected to the AC power source to act, open the valve, cold water or hot water enters the fan coil to provide air or heating to the room; when the room temperature reaches the temperature controller When the value is set, the thermostat de-energizes the electric valve, the return spring de-energizes the electric valve, and the return spring closes the valve, thereby cutting off the flow of water into the fan coil. By closing and opening the valve, the room temperature is always maintained within the temperature setting range.

Installation instructions

For high-rise buildings, a pressure reducing valve should be installed on the bottom branch pipe

The motor housing should prevent dripping from penetrating, so the drive must not be under the pipe when the valve is installed.

When the valve is mounted on a vertical pipe, the motor casing should prevent dripping

Manual joystick: When the handlebar moves slowly along the arrow and holds it in the notch, the valve is normally open. Whenever the current passes the electric valve for the first time, the manual lever will be reset to the automatic position.

If the drive is not pre-installed on the valve body, you need to install it. Push the drive into the lower groove in the direction of the arrow. Press the black button on the side of the drive and release it on the valve body to install it. If you need to disassemble, please repeat the appeal operation.

Note: The direction of water flow should be the same as the arrow on the valve body; when installing, the drive should not be used as the fulcrum of the force.

Installment

JSP74JAH differential pressure controller

The JSP74JAH differential pressure controller combines two pressure elements with high sensitivity, which, when changed, cause the switching mechanism to act to control equipment such as motor-driven valves. The switching mechanism provides SPDT non-fast sitting (floating) action, so the shared movable contact will contact one of the two fixed contacts or stay in between (meta contact).

Application range

1. JSP74JAH differential pressure controller is applied to the water system to control the pressure difference between the water pipe and the return pipe. After the controller's SPDT floats the contact point, the motor drives the longitudinal valve. A typical application is to install the valve in a bypass line near the system pump. When the system pressure difference increases and exceeds the controller set value, the valve is then opened larger, more water is diverted through the bypass valve, so that the system pressure difference is reduced, the pressure difference is reduced, the valve starts to close and the system is closed. The pressure difference increases.

2. In case of operational errors, possible systems (alarms, monitoring systems) that can cause personal injury or property damage, and alert when out of control. It is the responsibility of the installer to add facilities (safety, limit control) and protect them.
