Product Description
The D81X-16Q Handle Grooved Butterfly Valve is part of a new series of grooved (clamp) connection valves designed and manufactured based on advanced products from the United States and Germany. They feature quick, simple, safe, and reliable installation; are not restricted by installation site conditions; facilitate maintenance and repair of pipelines and valves; provide vibration and sound insulation; and can compensate for misalignment in pipeline connections within a certain angle range, as well as address thermal expansion and contraction caused by temperature differences. They are widely used in fluid conveyance pipelines for water supply and drainage, fire protection, air conditioning, gas, petroleum, chemical, water treatment, municipal, and shipbuilding pipeline projects to control fluid flow.
Product Features
- Grooved-handle butterfly valves feature a compact design, small size, light weight, flexible operation, and easy maintenance.
- Butterfly valves provide reliable sealing performance and are not affected by the direction of the medium flow, enabling bidirectional sealing.
- Large flow cross-sectional area, low flow resistance, and high flow capacity.
- The tray is made of a single piece of rubber-coated material that is resistant to aging and radiation, ensuring long-lasting durability.
