In the fields of fluid dynamics, combustible gas safety, and automation, the 1/2 Normally Closed (NC) Solenoid Valve serves as a critical component. Designed to automatically stop fluid or gas flow in the event of power loss or signal input, these valves are key to preventing industrial disasters, gas leaks, and chemical spills. Our engineering team at Xinhaosi designs these valves using premium components to meet strict global safety requirements.
Normally Closed solenoid valves use a balanced system of spring force and electromagnetic fields to control a movable plunger. Our 1/2-inch NC valves are built for reliability across different pressure ranges:
Corrosive gases and liquids require careful material selection. We use high-grade alloys and polymers to extend the operating life of our valves:
Highly resistant to chemical corrosion and acidic environments. Ideal for pharmaceutical and petrochemical applications.
High thermal stability and structural durability. Excellent for utility water systems, clean air, and non-corrosive gases.
FKM (Viton) and EPDM gaskets provide low gas permeability and withstand high temperatures from -20°C to 120°C.
Different industrial systems present unique engineering challenges. Our 1/2 Normally Closed Solenoid Valves are configured for specific applications to ensure safe operation under demanding conditions:
In city natural gas grids, solenoid valves prevent gas build-ups in homes and commercial kitchens. In these systems, 1/2-inch solenoid valves are connected to household combustible gas detectors (such as our JT-AT3068 Series). If a gas leak is detected, the controller triggers the valve to shut off the gas flow, protecting lives and property.
Underground mining operations are subject to strict explosion safety regulations due to potential pocket gas releases. Our flameproof solenoids are certified to ATEX and IECEx standards, and function reliably in hazardous areas alongside mining gas monitoring equipment like our GT-AT0616 Series.
In refineries and chemical processing plants, precision fluid control is crucial. Our heavy-duty solenoid coils are designed for 100% continuous duty cycles. This ensures they run cool and perform reliably, preventing overheating and premature failure in critical control systems.
Designed for immediate response at low operating pressures.
Optimized for high-pressure systems that require higher flow rates (Cv values).
Xinhaosi Electronic Detection Technology Co., Ltd. (founded in 2003) maintains complete control over the production process. This vertical integration allows us to supply high-quality components and reliable products to our B2B partners worldwide:
Modern industrial systems require connected components rather than isolated hardware. Our technology development plan focuses on integrating solenoid controls with digital industrial communication systems:
Modern valves can output their real-time state (open, closed, or faulted) directly to PLC or SCADA monitoring networks.
Built-in current sensors monitor coil health and warn operators about potential electrical issues before failure occurs.
Energy-saving designs reduce steady-state power consumption by up to 70% once the valve is open, minimizing heat build-up.
Founded in 2003, Xinhaosi is a trusted brand in the gas safety industry. We provide advanced products and services designed to safeguard factories, municipal infrastructure, and homes. Leveraging modern production systems and safety engineering, we deliver precise gas safety solutions for a safer future.
Detection Systems and precision sensing to protect industrial environments.
Gas detectors designed to monitor safety inside homes and commercial buildings.
Fast-acting shut-off systems that isolate hazard sources quickly.
Smart sensing networks designed for city-wide natural gas distribution infrastructures.
A Normally Closed (NC) valve stops fluid flow when the electrical power is disconnected. It only opens when energized. A Normally Open (NO) valve allows fluid to pass when there is no power, and closes only when electrical voltage is applied to the coil. NC valves are commonly used for safety shut-offs because they automatically close if power is lost.
Yes, but you must select the appropriate body and seal materials. For corrosive media, we recommend choosing our 316 Stainless Steel valve body combined with FKM (Viton) or PTFE seals. Avoid using brass or NBR with acidic or highly alkaline solutions.
We supply coils in standard industrial configurations: 24VDC, 110VAC, and 220VAC. We also offer explosion-proof, low-power, and continuous duty-cycle coils for specific applications.
Our solenoid valves can connect directly to safety controllers, like the JB-TB-AT2020LH, or gas detectors. When a detector senses combustible gas concentrations above safety thresholds, it cuts power or sends a signal to the valve, closing the line and securing the area.
