Gate valves
Elements presented below are designed to block or start the flow of industrial fluids or gases in pipelines like fire protection, agriculture or sewage installations. Gate valves are not suited to be used as control elements. They should work in completely open or completely closed position. An intermediate position is not permitted. The gate valve permits the flow by lifting a special disc, of rectangular or round shape.
Our valves are delivered with a handwheel. They are also ready for drive assembly and do not require special modifications. Products provide high tightness and are made of solid, durable materials, like nodular cast iron or grey cast iron. Before placing the order, we recommend checking the technical data sheet and the user’s manual provided for each element.

Why gate valves are essential for fluid shut-off systems
Gate valves are fundamental components in fluid handling systems, designed primarily for complete shut-off rather than flow regulation. Their construction allows minimal pressure loss when fully open and ensures a tight seal when closed, making them ideal for isolating a wide range of fluids under varying conditions. Industrial gate valves are crucial for maintaining system integrity, offering consistent performance in water networks, energy facilities, chemical plants, and beyond.
Industrial gate valves built for durability and efficiency
Zetkama’s range of industrial gate valves is engineered to meet the highest standards of performance and reliability. Available in nominal diameters from DN 15 to DN 1400, and designed to operate under pressures up to PN 40 or ANSI Class 800, these valves can withstand temperatures ranging from -29°C to +450°C, depending on the material configuration. Options include grey cast iron for general water and HVAC systems, nodular cast iron for enhanced mechanical strength, and forged or cast steel for high-pressure, high-temperature operations. Each gate valve is designed with flanged or welded ends compliant with EN and ANSI standards, ensuring easy integration into complex piping systems.
Heavy duty gate valve solutions for critical installations
In installations where operational demands are exceptionally high, a heavy duty gate valve becomes indispensable. Zetkama offers heavy duty gate valves equipped with fusion-bonded epoxy coatings, thick up to 300 microns, providing outstanding protection against corrosion, abrasion, and chemical attack. Designed with Class A sealing tightness according to EN 12266-1, these valves guarantee leak-free performance even under extreme conditions. Heavy duty models are ideal for use in power generation, district heating, petrochemical facilities, and marine systems, where reliability and longevity are paramount.
Brass gate valve applications for versatile fluid control
For potable water systems, HVAC installations, and low-pressure networks, the brass gate valve offers a corrosion-resistant, mechanically robust solution. Brass construction ensures compatibility with drinking water standards, while maintaining excellent resistance to dezincification and wear. Zetkama’s brass gate valves are precision-machined to ensure easy operation and tight shut-off, providing a dependable choice for both commercial and residential systems requiring durable yet cost-effective isolation valves.
Key features and operational advantages of gate valves
Zetkama gate valves provide significant operational benefits across all sectors. Designed for manual operation via handwheel, they offer straightforward and reliable functionality. For larger or automated systems, electric actuator options are available to enable remote or integrated control. Gate valves can be installed in any orientation without affecting performance, offering maximum flexibility during system design. Their robust construction ensures minimal flow resistance when fully open, resulting in energy-efficient operation. Long service life is achieved through the use of high-grade materials, precise manufacturing processes, and advanced protective coatings that shield against aggressive environmental and operational factors.
Typical applications for industrial and heavy duty gate valves
Gate valves are widely deployed in critical infrastructure and industrial settings. In water supply systems, they ensure secure isolation of distribution lines for maintenance and operational control. In the energy sector, they are key components in steam, heating, and thermal oil circuits. Chemical and petrochemical industries use gate valves to manage the flow of aggressive liquids and gases, maintaining safety and operational efficiency. In HVAC installations, marine engineering, and compressed air systems, gate valves provide reliable shut-off solutions that stand up to demanding service conditions, ensuring system longevity and performance stability.
