Coliter ® Magnetic Gate Valve – PN16, -20~180°C, Stainless Steel Body with Magnetic Locking for Water, Gas & Chemical Media
HCSZ15E Magnetic Gate Valve – Threaded Gate Valve with Integrated Magnetic Lock and 304/CF8 Construction
The Coliter® HCSZ15E Magnetic Gate Valve is a high-performance, tamper-resistant gate valve designed for secure flow control in water, gas, oil, nitric acid, acetic acid, and other industrial media. Constructed entirely from corrosion-resistant materials—CF8 (304 stainless steel) for the body, bonnet, and flashboard, and 304 stainless steel for the stem, packing bushing, and magnetic device—it ensures long-term reliability in aggressive environments. The valve features an integrated magnetic locking mechanism that prevents unauthorized operation; it can only be opened or closed using a dedicated magnetic tool, making it ideal for utility metering, public infrastructure, and chemical handling systems. Rated at PN16 (1.6 MPa), it undergoes rigorous testing: shell test at 2.4 MPa, seal test at 1.76 MPa (water), and hermeticity test at 0.6 MPa (air). It operates reliably within a wide temperature range of -20℃ to 180℃. The valve uses ISO 228 cylindrical pipe threads (G1/2" to G2") for sizes DN15–DN50 and complies with Chinese standards GB/T 12224 (design), GB/T 12221 (structure length), and GB/T 13927 (testing). With PTFE sealing elements and a compact non-rising stem design, the HCSZ15E delivers zero leakage, maintenance-free operation, and enhanced security in residential, commercial, and industrial fluid control applications.

Introduction to Cast steel gate valve
Coliter®’s cast steel gate valves, including the Z40H (non-rising stem) and Z41H (rising stem) models, are designed for high-pressure, high-temperature applications in oil & gas, power generation, chemical processing, and district heating systems. Constructed from WCB (A216) cast steel with a bolted bonnet design, these valves feature a metal-seated wedge disc for reliable shut-off under severe service conditions. Rated at PN16 to PN40 (1.6–4.0 MPa) and suitable for temperatures up to 425°C, they comply with API 600, GB/T 12234, and ASME B16.10 standards. Full-port flow, fire-safe design, and robust construction ensure long-term performance in critical industrial pipelines.
