ZZWPE self-operated temperature control valve is suitable for various heat transfer conditions in which steam, hot water, hot oil and other media are used. Widely used in heating, air conditioning, domestic hot water temperature automatic regulation, as well as special conditions of temperature automatic regulation, such as chemical, textile, pharmaceutical and other production projects. It is suitable for various heat exchange conditions with steam, hot water and hot oil as the medium. Widely used in heating, air conditioning, domestic hot water temperature automatic regulation, as well as special conditions of temperature automatic regulation, such as chemical, textile, pharmaceutical and other production projects.

Characteristic：

1. Actuator products which can automatically adjust the temperature of the medium by using the energy of the medium itself without any additional energy.
Wide range of temperature setting, clear display, high accuracy, and overload protection device, safe and reliable, so it should be widely used in chemical industry, petroleum, electricity, metallurgy, food, textile, civil buildings, hotels, restaurants and other heating, water supply, refrigeration, sterilization and other equipment temperature automatic regulation. 。

Application scope：

Self-operated temperature control valve, also known as temperature control valve, self-operated temperature control valve, temperature control valve, temperature control valve. It consists of control valve and temperature controller. According to its use, it can be divided into heating type and cooling type. Self-operated temperature control valve is mainly composed of control valve and temperature controller. It is an energy-saving product that can automatically adjust the temperature change of controlled medium without external energy. Suitable for non-corrosive liquid, gas and steam, temperature control in various cooling systems. When the temperature of controlled medium rises, the control valve closes (heating type); when the temperature of controlled medium rises, the control valve opens (cooling type).

Key Points of Design Selection

(1) First determine whether the controlled medium is oil or water.
(2) Calculate the flow rate m3/h of the controlled medium.
(3) Choose the caliber of three-way temperature regulating valve according to the controlled medium and its designed flow rate.
(4) According to the material of valve body (cast copper or T cast iron), connection form (F flange, G pipe thread, ZG taper pipe thread), valve structure type (Z rotary valve, H slide valve), temperature regulation range and installation type, the type of three-way regulating valve is determined.
(5) According to the different flow directions of the three valve orifices, the three-way temperature regulating valve can be used in confluence or shunt control occasions.
(6) The function of the combined three-way temperature control valve is to mix two different temperature fluids through the valve into a third temperature between the two. The valve has two inlets (B is a high temperature inlet, C is a low temperature inlet) and one outlet (A). The temperature sensor is installed at the outlet (A). The function of the split-flow three-way temperature control valve is to divide a fluid into two parts proportionally after passing through the valve. When the valve closes one outlet, it opens another outlet. The valve has one inlet (A) and two outlets (B is bypass return port, C is split cooling port).
(7) The three-way temperature regulating valve can replace a two-way valve and a three-way nozzle.
(8) There are six installation types of rotary valve three-way temperature regulating valve, which can be adapted to any pipe connection. The installation type is selected according to the actual pipe connection of the system.
(9) The three-way temperature regulating valve can be installed at any position, but the emergency manual device surface should be installed at a convenient position.
(10) In order to prevent the entrapment or blockage of impurities in the medium, the three-way temperature regulating valve should be equipped with a filter in front of the valve.
