Product Overview

TheElectric Steam Temperature Control Valve is a high-performance, self-operated electric temperature regulating valve designed for precise automatic temperature control in steam, hot water, thermal oil, and gas systems. Comprising three core components — the control valve body, intelligent electric actuator, and temperature sensor (PT100 thermocouple) — this system delivers accurate, reliable temperature regulation without the need for complex external control instrumentation. The valve requires only a standard 220V power supply and utilizes the energy of the regulated medium itself to achieve fully automatic temperature adjustment. Available in sizes from DN25 to DN300 (NPS 1″ to 12″) with pressure ratings from PN16 to PN100 (150LB to 600LB) and a wide temperature range from -20°C to 450°C, this valve is suitable for a broad spectrum of industrial applications. With multiple body material options (WCB/WCC/WC6/CF8/CF8M/CF3M), seat materials (304/316/316L with Stellite hardfacing), and flow characteristics (linear, equal percentage, quick opening), the ZZWPE series offers flexible configuration to meet diverse process requirements. Backed by CE, RoHS, and ISO 9001 certifications, it is the trusted choice for chemical, petrochemical, pharmaceutical, food processing, HVAC, and power generation industries.

Working Principle

The ZZWPE electric temperature control valve operates through a closed-loop control system comprising three core components: the control valve body, the intelligent electric actuator, and the temperature sensor (PT100 thermocouple). The system is available in both heating-type and cooling-type configurations:

Heating-Type Operation: The valve is normally open. When the medium temperature rises to the setpoint, the sensor sends a linear signal to the actuator, which drives the valve stem to close proportionally, reducing the steam/thermal oil flow and stopping further temperature rise. When the temperature drops below the setpoint, the actuator opens the valve to restore heating.

Cooling-Type Operation: The valve is normally closed. When the medium temperature rises above the setpoint, the actuator opens the valve to allow cooling medium flow, reducing the process temperature.

FAQ

Q1: What is the difference between a self-operated electric temperature control valve and a standard electric control valve?

A: The self-operated electric temperature control valve consists of three components—a control valve, an intelligent actuator, and a temperature sensor—and is designed specifically for temperature control. It requires only a 220V power supply and utilizes the energy of the controlled medium itself to achieve automatic temperature regulation. While standard electric control valves typically require an external controller to provide control signals, the self-operated electric temperature control valve integrates temperature sensing and closed-loop control functions, resulting in easier installation and lower costs.

Q2: What is the difference between the heating type and the cooling type?

A: Heating-type valves close when the temperature rises (reducing the flow of the heating medium) and open when the temperature falls (increasing the flow of the heating medium). Cooling-type valves open when the temperature rises (increasing the flow of the cooling medium) and close when the temperature falls. The choice depends on whether your process requires heating or cooling.

Q3: What is the difference between a single-seat valve and a sleeve valve?

A: Single-seat valves are suitable for applications with low pressure differentials, high-viscosity media, or media containing minor particulate impurities. Sleeve valves (cage-guided valves) are suitable for applications with high pressure differentials. Sleeve valves utilize a balanced plug structure, which significantly counteracts the unbalanced forces generated by fluid flow, thereby reducing the load on the actuator.

Q4: Can this valve be used for superheated steam?

A: Yes. The ZZWPE series is suitable for various media, including steam (including superheated steam), hot water, thermal oil, and gases. For superheated steam applications, a high-temperature configuration (featuring a heat-dissipating bonnet) is recommended, allowing for operating temperatures up to 450°C.

Q5: Can the lengths of the temperature sensor and capillary tube be customized?

A: Yes. Standard capillary lengths are 3 meters, 5 meters, and 10 meters, but these can be customized based on on-site installation requirements. The installation position of the temperature sensor (sensing bulb) and the probe length can also be customized according to process specifications.
