ZZWPE Self-electric Temperature Control Valve product details

ZZWPE Self-electric Temperature Control Valve product description:

ZZWPE Self-electric Temperature Control Valve (for larger caliber and thermal oil control) produced and sold by Baigang valve group, the valve features only the most common 220V power supply, the use of the media itself is adjusted to the energy directly to the steam, hot water, hot oil and gas and other media The temperature of the implementation of automatic regulation and control, can also be used to prevent overheating or heat exchange occasions, the valve structure is simple, easy to operate, the selection of a wide range of temperature control, fast response time, reliable sealing performance, and can be adjusted during operation , Which is widely used in chemical, petroleum, food, textile, hotels and restaurants and other departments of hot water supply.

ZZWPE Self-electric Temperature Control Valve part Information:

◆ Structure and Principle
Control valve consists of main valve, intelligent actuator and sensor composed of three parts, according to user needs, respectively, heating and cooling of two structures.
1. The structure and principle of the heating control valve, see the attached diagram:
Before work, the main valve core is in the half-open position and the sensor is in a natural state. Connect the power, the main spool fully open. The medium flows into the main valve body in the direction of the arrow, and the heat storage tank is heated by the valve core. When the temperature rises to the corresponding set value, the sensor generates a corresponding linear signal input integrated intelligent actuator, then drive the stem, the valve spool displacement, turn off the main valve to stop heating. When the temperature is lower than the set value, the sensor generates a linear signal input to the actuator, which drives the valve element to be involute, allowing the medium to flow into the thermal storage tank according to the parabolic characteristic and heating up to the set value. This controlled media is always in the set temperature range is controlled, so as to achieve the purpose of temperature control.
