Gate valves play an essential role in controlling the flow of liquids and gases in many industrial and commercial applications. When it comes to applications involving potable drinking water, the valves used must meet stringent standards to ensure the water is safe and fit for human consumption without contamination. The Water Regulations Advisory Scheme (WRAS) in the UK is responsible for certifying products, materials and components that come into contact with the medium (Drinking water). Our TTV WRAS-approved gate valve offers several unique features that make it an excellent choice for potable water applications.
One of the most significant advantages of the TTV WRAS-approved gate valve is its materials of construction. The valve body is made of a high-quality GJS 400-15 Ductile Iron, which is known for its strength, durability, and corrosion resistance with a 300 micron internal and external epoxy coating. The gate of the valve is also constructed of GJS 400-15 Ductile Iron with a fully encasulated EPDM or NBR vulcansied runner. This is an excellent material for use in potable water applications due to its corrosion resistance and hygiene properties.
Another key feature of the TTV WRAS-approved gate valve is its leak tight design. The valve is designed to provide complete shut off and smooth operation, with minimal friction and easy manual operation throguh the ergonomic handweheel. This makes it easy to install and maintain, with minimal downtime required for repairs and replacements.
Internal and external body coatings are finished with a high quality 300 micron epoxy paint, wras approved for use with potable drinking water applications. The stainless steel stem and internal bronze trim extend the life cycle of the gate valve with their corrosive resistant materials and offer a low torque operation on all valves tested to 100% tight shutoff EN 12266/ISO 5208.
Overall, the TTV WRAS-approved gate valve is an excellent choice for any application involving potable water. Its high-quality construction, tight seal, smooth operation, and energy efficiency make it a reliable and cost-effective solution for water supply systems. Whether you are designing a new system or replacing existing valves, the TTV WRAS-approved gate valve is a smart choice that will ensure the long-term safety and reliability of your water supply system.
