High Temperature Thermal Oil Solenoid Valve for Chemical Plastic Rubber Industrial Heat Transfer System Suppliers Manufacturers

High Temperature (Thermal Oil) Solenoid Valve

An automatic control valve specifically designed for thermal oil systems (medium temperature can reach 300-550 ℃ or even higher), which drives the piston structure through electromagnetic force to achieve remote on/off control of high-temperature thermal oil.

Core Features

Ultra high temperature resistant design: The valve body is made of stainless steel/alloy material, suitable for media such as 300-650 ℃ high-temperature thermal oil and molten salt;

Zero leakage hard seal: metal valve core+fluoroplastic (PTFE) or metal piston ring seal, completely eliminating high-temperature medium leakage;

Anti burn coil: External heat dissipation module (such as air-cooled shell) ensures that the coil temperature is ≤ 85 ℃ to avoid high temperature demagnetization;

High pressure adaptability: The piston pilot structure supports a pressure difference of 0.1~40MPa, with an opening and closing time of ≤ 1 second.

Intelligent heat dissipation and burn prevention

Intelligent heat dissipation and burn prevention
01
External heat dissipation module for the coil (such as air-cooled casing or high-temperature resistant electrical materials), with a continuous working coil temperature of ≤ 85 ℃, to avoid high temperature demagnetization and burnout.

Long service life

Long service life
01
The piston and valve chamber are designed with no direct friction, coupled with wear-resistant piston rings, with a service life of over 1 million times and support for high-frequency switching actions.

Design of corrosion-resistant materials

Design of corrosion-resistant materials
01
The key components (valve body, valve plug) are made of 316 stainless steel or copper alloy, which is resistant to acid and alkali corrosion and compatible with corrosive media such as thermal oil and chemical solvents.

High voltage strong adaptability

High voltage strong adaptability
01
The working pressure difference reaches 0.1~40MPa, and the piston type pilot structure uses fluid pressure to assist in opening and closing. It can still respond quickly (≤ 1 second) under high pressure conditions.

Zero leakage hard sealing technology

Zero leakage hard sealing technology
01
Adopting a metal hard seal (such as stainless steel valve core+metal piston ring) or fluoroplastic (PTFE) sealing structure, it is wear-resistant, heat-resistant, and completely eliminates the leakage of high-temperature media.

Extremely wide temperature resistance range

Extremely wide temperature resistance range
01
Suitable for medium temperatures ranging from -40 ℃ to+650 ℃ (conventional models ≤ 550 ℃), the valve body is made of stainless steel or alloy material, and is designed with a heat dissipation structure to ensure stable control of high-temperature heat transfer oil, molten salt and other media.
