The ZCF-X and ZCF-PX Series (DN15-50) Large Orifice Pilot-operated Diaphragm Type Anti-corrosive Explosion-proof Solenoid Valve is a premium, high-performance fluid control component explicitly engineered for mid-to-large diameter pipelines in punishing and hazardous environments. In sectors such as petrochemical refining, fine chemical distillation, semiconductor wet processing, pharmaceutical manufacturing, and continuous industrial wastewater treatment, there is a critical need to safely and precisely control the large-volume flow of highly aggressive, volatile, and explosive fluids. This series innovatively integrates a pilot-operated diaphragm mechanism, advanced fluorinated/perfluorinated elastomer material technology (FKM/EPDM/FFKM), and certified explosion-proof electrical design (Ex). The valve implements a pilot structure that utilizes the pipeline fluid pressure to facilitate actuation, perfectly overcoming the challenge of insufficient shut-off force faced by large-diameter valves under differential pressures. Simultaneously, the heavy-duty elastomeric isolation diaphragm creates an absolute physical barrier between the corrosive media in the pipeline and the internal metallic core, spring, and electrical components. This state-of-the-art design not only immunizes the valve from internal corrosion but completely eliminates the risk of catastrophic explosions caused by volatile media leaking into contact with electrical sparks, ensuring unparalleled operational safety.Product Image:ZCF-X Piston Type Anti-corrosive Explosion-proof Solenoid Valve

ZCSB flameproof solenoid valve is an automated execution element used in industrial control systems to manage the opening and shutting of fluid media. The valve consists of a high-performance electromagnetic coil and a precision valve body structure. It generates electromagnetic force upon receiving electrical signals to drive the plug or diaphragm for rapid displacement. The core advantage of the ZCSB series lies in its integral flameproof enclosure, which effectively prevents internal electrical sparks from igniting flammable or explosive atmospheres, meeting strict explosion-proof standards. With a compact design, extremely agile response, and excellent sealing performance, it is widely used in hazardous locations such as petroleum, chemical, natural gas, refueling stations, and mines.Product Image of ZCSB Explosion-proof Solenoid Valve

The ZCF Series (DN2-8) Micro-flow Diaphragm Type Anti-corrosive Explosion-proof Solenoid Valve is a premium, high-performance fluid control component explicitly engineered for the most punishing and hazardous environments in modern process industries. In sectors such as fine chemical synthesis, semiconductor wet processing, pharmaceutical manufacturing, and continuous emissions monitoring systems (CEMS), there is a critical need to safely and precisely control the micro-flow of highly aggressive, volatile, and explosive fluids. This series innovatively integrates a direct-acting driving mechanism, total fluoropolymer isolation technology (PTFE), and certified explosion-proof electrical design (Ex). The valve implements a heavy-duty, highly flexible isolation diaphragm that creates an absolute physical barrier between the corrosive media in the pipeline and the internal metallic core, spring, and electrical components. This state-of-the-art design not only immunizes the valve from internal corrosion but completely eliminates the risk of catastrophic explosions caused by volatile media leaking into contact with electrical sparks, ensuring unparalleled operational safety.Product Image:ZCF Diaphragm Type Anti-corrosive Explosion-proof Solenoid Valve

The ZCSB series flameproof 2-way 2-position explosion-proof solenoid valve (nominal diameter ranging from DN10 to DN200) is a high-safety rating execution device specially designed and developed for inflammable, explosive hazardous environments, high-reliability industrial pipe networks, and heavy-duty multi-medium fluid automated control. As a core execution element in petrochemical industries, natural gas transmission and distribution, coal mine gas drainage, gas station liquid level control, and specialized inflammable gas pipelines, this series features comprehensive structural reinforcement targeting high pressure bearing conditions up to 16bar (1.6MPa) and complex on-site electrical explosion-proof environments. It focuses on solving fatal potential hazards where traditional solenoid valves generate electrical sparks during coil switching or short circuits that induce instantaneous explosions of external environments. It also addresses industry difficulties under large-bore high-pressure environments, such as sealing failures and actuation stagnation when conveying viscous oil products, high-temperature steam, or corrosive liquids. The series provides two driving mechanisms: direct acting (small bore) and semi-direct acting (large bore) based on the bore span, and the entire series is equipped with a specialized heavy-duty flameproof enclosure certified by national explosion-proof authorities. Valve body materials cover premium brass, high-purity SS304 stainless steel, and heavy-duty cast iron (where versions with the "F" suffix represent large-specification flange versions). Interfaces perfectly support G/NPT threads and international standard flanges, fully satisfying production safety needs in specialized hazardous industrial fields. This series of valves belongs to normally closed 2-way 2-position automatic valves. Its core essence lies in the seamless combination of electrical flameproof enclosure rigid safety blocking technology and robust 16bar bidirectional sealing shut-off characteristics. When the electromagnetic coil is de-energized, an ultra-high rigidity main return spring applies direct rigid pre-tightening force through the linkage shaft, pressing the specialized high-density wear-resistant sealing assembly tightly against the main valve seat. Because the nominal pressure of this series reaches up to 16bar, the heavy-walled valve body and powerful spring can perfectly resist violent impacts generated by high-pressure fluids during reverse or forward flow, achieving absolutely reliable and long-lasting zero-leakage physical obstruction. When the electromagnetic coil is energized, the electromagnet located inside the specialized explosion-proof chamber instantly generates a powerful magnetic field attraction force. For small-bore direct acting structures, the moving iron core directly overcomes spring resistance to lift the valve core rigidly; for large-bore semi-direct acting structures from DN50 to DN200, the back-kick mechanical linkage assembly first opens the internal balancing pilot hole to quickly relieve the high-pressure medium above the main valve core, and then rigidly lifts the main sealing assembly. Even if the system pipeline is under an extreme condition of zero pressure differential without any pressure difference, or when pressure fluctuates violently within 16bar, the valve is rigidly and linkedly controlled by the electromagnetic assembly and mechanical structure. The switching response speed reaches millisecond levels, effectively avoiding valve switching lags caused by insufficient pressure differential or oil product viscosity damping in large-specification high-pressure bearing environments of ordinary pilot valves.Product Image:ZCSB Explosion-Proof (Flameproof) 2/2-Way Solenoid Valve
