Rising and Non-Rising Gate Valve in Saudi Arabia

Rising stem or non-rising stem gate valves are the two categories. The stem is referred described as “rising” if it does so as the valve is opened and protrudes through the valve bonnet. Regardless of the valve position, “non-rising” describes a stem that does not rise from the valve bonnet. Disc and stem are both removed from the flow channel by rising stem designs when the valve is open. When the valve is open, non-rising stem designs often leave the stem in the flow channel, however, it is also feasible to entirely house the stem inside the disc. In corrosive environments, such as sea spray, where it is not ideal to have the stem permanently exposed when the valve is open, non-rising stem gate valves are preferable in Saudi Arabia.
