The stable operation of each piece of equipment is the best proof of Hengchun's product quality. Given the characteristics of continuous production and difficulty in shutdown in the refining and chemical industry, Hengchun actuators, with reliable operation time and time again, escort enterprises' safe production and economic benefits.
In the refining and chemical industry, PetroChina and Sinopec, as industry leaders, have extremely strict access standards and quality requirements for suppliers. With excellent product quality and a comprehensive service system, Hengchun Electronics has successfully entered the supplier lists of both central SOEs and become their long-term partner.
· PetroChina: Hengchun actuators are widely used in refining and chemical units of various refining and chemical branches
· Sinopec: From large refining and chemical bases like Zhenhai Refining and Maoming Petrochemical to refining and chemical enterprises across the country, Hengchun products can be seen everywhere
At the same time, among the rapidly developing private petrochemical enterprises, Hengchun actuators have also gained wide recognition. In large private refining and chemical integration projects such as Zhejiang Petrochemical, Hengli Petrochemical, and Shenghong Petrochemical, the presence of Hengchun actuators can be seen. Whether it's central SOEs or private enterprises, large bases or small and medium-sized units, Hengchun Electronics can provide adapted products and professional services.

· On-off type, regulating type, intelligent type, and other functional configurations
· Standard type, explosion-proof type, anti-corrosion type, high-temperature type, and other environmental adaptations
The refining and chemical industry has complex and diverse operating conditions — high temperature, high pressure, flammable and explosive, strong corrosion... each condition is a severe test for equipment. Over years of industry application, Hengchun actuators have withstood the test of various harsh conditions:
· High Temperature Conditions: From temperatures above 350°C at the bottom of atmospheric-vacuum towers to ultra-high temperatures above 800°C at ethylene cracking furnace outlets, Hengchun actuators operate stably
· High Pressure Conditions: 15-20MPa high-pressure environment in hydrogenation units, severe erosion of high-pressure differential control valves — Hengchun products reliably handle them all
· Explosion-Proof Requirements: Refining and chemical plant areas are mostly explosion-proof zones. Hengchun explosion-proof actuators meet various explosion-proof grade requirements, ensuring production safety
