I. Core Technical Features and Design Principles
Pressure Control Technology
Utilizes multi-stage pressure reduction sleeves or similar structures. The principle of staged pressure reduction effectively decomposes high-pressure drops, controls flow velocity, and minimizes damage to valve internals caused by cavitation and flashing.
Materials Science and Surface Treatment
Critical internal parts like the valve plug and seat often use base materials such as stainless steel or duplex steel, with Stellite alloy hardfacing applied to enhance wear and corrosion resistance. Valve stem surfaces undergo special hardening treatments, achieving hardness up to HRC 55 or higher.
Temperature Adaptability Design
Ensures reliable sealing and smooth operation across an extreme temperature range of -320.8℉ to 1112℉ through precise calculation of thermal expansion coefficients, selection of wide-temperature-range materials, and special designs like flexible seats or floating seals (e.g., the floating stuffing box structure in high-temperature gate valves).
Actuator Matching
Offers actuator options including pneumatic (diaphragm/piston) and electric. Explosion-proof pneumatic control valves are designed for hazardous areas, typically possessing international explosion-proof certifications and being noted for fast response times and high control accuracy. (Please refer to the latest technical manual for specific parameters).

II. Summary of Technical Specifications for Main Product Series
Imported Electric Control Valve
Focuses on high-precision flow regulation. Offers high accuracy for characteristic curves like equal percentage and linear. Internal design helps reduce fluid noise.
Explosion-Proof Pneumatic Control Valve
Features both linear and rotary stroke options, suitable for hazardous areas. Key indicators include explosion-proof rating, response time, and control accuracy.
High-Temperature Gate Valve
Employs a fully floating seal device, allowing the valve stem and stuffing box to micro-adjust radially to compensate for thermal displacement, effectively solving high-temperature stem leakage issues.
Electric Control Diaphragm Valve
Streamlined flow path design results low pressure loss. Diaphragm movement has a self-cleaning effect, preventing particle accumulation. Suitable for slurries, viscous media, or applications requiring cleanliness.
