**Product Description** Gate valves are specifically engineered for on-off service applications. These valves comprise a body, bonnet, gate, stem (featuring an internal screw and yoke), a rising stem equipped with a non-rising handwheel, and an integral seat as standard. Additionally, there are options available for renewable seats, along with an open and closed indicator, complete with a lockable handwheel. --- **Features** Gate valves provide reliable shutoff capabilities with minimal pressure drop, rendering them perfect for regulating liquid or gas flow across diverse applications. Their sturdy construction promotes high efficiency and easy maintenance, thanks to their uncomplicated design. Gate valves can be manually operated or automated using devices such as motors, solenoids, or actuators. When the gate is in the closed position, it serves as an effective barrier, preventing flow. In contrast, when opened, the gate retracts from the seat, permitting unrestricted flow through the valve. Once closed, fluid movement is entirely halted. --- **Materials** - **Body/Bonnet**: NAB (ASTM B148 C95800) - **Stem**: NAB (ASTM B150 C63200) / MONEL (ASTM B865 N05500) - **Handwheel**: Stainless Steel (ASTM A351 CF8M) --- **Technical Data #150/PN32** - **Design Standard**: MSS SP 80 / BS 5154 / BS EN 12288 - **Size**: DN15 to DN80 - **End Connection**: ASME B1.20.1 - **Face To Face**: As per manufacturer specifications - **Testing**: EN 12266-1, API 598 - **Max Pressure**: 19 / 32 BAR - **Min Temperature**: -29°C / -10 to 66°C - **Max Pressure**: 7.9 / 14 BAR - **Min Temperature**: 260°C - **Material Test Certification**: BS EN 10204-3.1 --- **Technical Data #300** - **Design Standard**: MSS SP 80 / BS 5154 / BS EN 12288 - **Size**: DN15 to DN80 - **End Connection**: ASME B1.20.1 - **Face To Face**: As per manufacturer specifications - **Testing**: EN 12266-1, API 598 - **Max Pressure**: 49.6 BAR - **Min Temperature**: -29°C - **Max Pressure**: 20.6 BAR - **Min Temperature**: 260°C - **Material Test Certification**: BS EN 10204-3.1 --- Optimise your operations with our premium-quality gate valves, designed for durability and efficiency.
