Price Range

Currently, the price of a carbon steel electric stop valve DN100 suitable for petrochemical engineering generally ranges from $250 to $900 USD. The final cost depends on several key factors:The main stop valve product names of China Stop Valve Network include:Electric Flange Straight-through Globe Valve,Forged Steel Straight-through Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,GB Cast Steel Flange Globe Valve,Manual Welding High Temperature and Pressure Globe Valve,Flange Straight-through Low Temperature Globe Valve,Pneumatic Flange Straight-through Globe Valve,Oxygen-specific Globe Valve.

Valve Body Material: WCB carbon steel is the standard choice, priced between $250 and $500. LCB low-temperature carbon steel is suitable for cold climates or low-temperature conditions, ranging from $500 to $700. WC6 alloy steel is used for high-temperature and high-pressure environments, costing between $700 and $900.

Electric Actuator: Standard on-off type actuators are lower in cost, while modulating type (4-20mA signal) and explosion-proof actuators significantly increase the price.

Sealing Surface Material: Stainless steel sealing surfaces offer good corrosion resistance, while cemented carbide sealing surfaces are more wear-resistant for highly erosive conditions.

Explosion-proof Rating: Petrochemical environments typically require Exd flameproof enclosures; higher explosion-proof ratings command higher prices.

Brand & Certification: Products with API, ISO, or TS certifications from reputable brands are more expensive than non-certified alternatives.

Selection Advice

Petrochemical media are often flammable, explosive, corrosive, or operate under high temperature and pressure. It is highly recommended to choose an explosion-proof electric actuator and verify the pressure rating (Class150 to Class600) and connection standard (ASME B16.5 or GB/T 9113) according to actual operating conditions. For media containing particles or with high viscosity, a cemented carbide sealing surface is recommended to extend service life.

Important Notes

An unusually low price may indicate substandard materials, non-explosion-proof actuators, or simplified sealing surfaces, posing leakage and safety risks. Always request material certificates, pressure test reports, and explosion-proof certification from suppliers to ensure the valve meets the stringent safety requirements of petrochemical engineering.
