Thermal Company Heat Exchanger Equipment Uses Electric Temperature Control Valve

VF45 High Closing Force Flange Type Two Way Regulating Valve

Composition of Temperature Control Valve:

• Consider valve material, flow capacity, and actuator shutoff force based on heat medium (steam/hot water), temperature, and pressure parameters.
• For steam flow control, calculations are based on 98% dryness. Superheated steam requires recalculation due to viscosity changes.
• Maintain appropriate differential pressure to prevent noise, cavitation, and potential safety hazards.
• Equal percentage or parabolic curves are recommended for optimal thermal system temperature regulation.
• Electric temperature control valves should not be used as stop valves; shut down during machine stoppage.
• Do not convert two-way valves to three-way valves by removing blind plates.
• Temperature control valves must be used in circulating systems. Instant heat exchangers require a storage tank.
• Distinguish between 24-hour and regular hot water supply for domestic applications.

1. Precision casting (resin sand) nodular cast iron GGG-50.
2. Pressure balance type valve body guarantees high clearance at low pressure and switching ability under high pressure difference.
3. Maximum allowable differential pressure is 1000kpa.
4. Stem seal uses special sealing process.
5. Full metal joint seat for increased valve life.
6. Meets GB/T17213-2015 flange connection standards.
7. Iron coated sand casting process ensures thick walls, no pores, and high density. The PTFE + carbon fiber sealing ring provides superior wear resistance and zero leakage.

Application: Suitable for Continuous Control in Regional Heating Systems and HVAC Systems. Compatible with SAX, SKD, SKB, and SKC series executors.
