Gate Valve
Wedge gate valves are products used in industrial installations to shut off the flow of liquids and gases. They find extensive application in various installations due to their characteristic construction. Our offered oval wedge gate valves have been crafted from high-quality materials, ensuring attention to detail. They are reliable products designed for use with various liquids and gases.
Gate valve – principles and method of operation
Wedge gate valves, known as gate valves, are industrial installation components used to control the flow of liquids and gases. Their broad application across diverse installations stems from their distinctive construction. Our offered oval wedge gate valves have been meticulously crafted from high-quality materials, ensuring reliability across various liquids and gases.
Raising or lowering the wedge controls the opening or closing of a section within the installation. This type of valve falls under the category of multi-turn valves, known for their slow operation that prevents hydraulic shocks. This means that the operation of this accessory is carried out using a threaded stem that rotates several times, transitioning from the open to closed position.
Application of gate valves – where can they be used?
Flanged gate valves are used in situations requiring minimal pressure loss and full flow. They find applications in chemical, mining, power generation, district heating, and water treatment industries. Gate valves vary in specific parameters, hence, it’s crucial to consider the characteristics and intended purpose of a particular type before making a purchase and choosing the installation location.
Flanged gate valve – structure
The flanged gate valve comprises a body, wedge, stem, cover, and sealing. In the valves we offer, all these components have been meticulously crafted, ensuring their tightness and reliability. Our valves comply with applicable standards and are highly practical. A soft-seated wedge gate valve stands out due to its smooth construction, allowing the free flow of sand and stones along the structure.
Among our valves, models with rising and non-rising stems are available. The former are permanently attached to the valve’s closing element, meaning they rise and lower simultaneously with the gate. Flanged gate valves with this type of stem are suitable only for above-ground installations. On the other hand, non-rising stems are threaded into the wedge, causing them to rise or lower the valve’s closing element. This type can be used both above and below ground.
Gate valves – properties and key features
The flanged gate valves available on our website are crafted from high-quality materials, ensuring their reliability. The parameters of each type indicate their specific applications, derived from the particular requirements they meet. Our website showcases valves with bodies made of carbon steel, stainless steel, and ductile iron.
These models are differentiated by their nominal pressure, categorized as low, medium, or high pressure. The gate valves are suitable for operating under various temperature conditions, ranging from -29°C to +425°C. This is a crucial parameter as different temperature requirements apply to applications involving drinking water, sewage, or gas flow.
