Non rising Stem - DZR Brass Plumbing Products

Non-Rising Stem - Lead-Free Brass Gate Valves are suited for general uses on water, compressed gas, oil or other applications. These valves have a non-rising stem, threaded bonnet and Lead-Free brass body. Their Lead-Free construction complies with installation requirements of Lead-Free.

The lead-free gate valves – Non-Rising Stem type need a very small space for operating while more space is needed by the rising stem variants of the gate valves. The Non-Rising valves have a construction that is designed in such a way that the stem of the gate valve remains completely open when the handle gets rotated to the farthest point on the left and completely closed when the handle gets rotated to the extreme right position. In both scenarios, the handle is flush with the pipe as the mechanism present inside the pipe closes and opens the valve without the stem getting raised. Another advantage of the NRS gate valve is that it becomes easy to lock it up. These types of gate valves are mainly used for gases and clean liquids. These valves are designed with non-rising stems that make them perfect to be used in applications where there is limited vertical space. This range of comprehensive Non-Rising Stem - DZR Brass Gate Valves are manufactured using a high-class range of brass, bronze and DZR brass that has exceptional resistance to corrosion.

Plumbing Gate Valves are known for their exceptional reliability and durability. These valves get closed or open at a very slow speed and will get completely closed or opened when they are not in operation for a long period of time. Due to these reasons, they have emerged as the preferred choice for applications of isolation in where the pressure increases are needed to be avoided and placed where the valve does not receive frequent use. All of the Gate Valves can be used in systems that involve the supply of drinking water while the bronze and DZR brass valves are mostly suited for chilled systems and low-temperature hot water. All the supplied by us for this range are WRAS approved. Data of performance including pressure-temperature rating are developed from published standards, specification of supplier material, testing is done in-house and calculations of design. They take over the conventional applications and are offered as a general guideline.
