Kiwa recently presented several clients with TMV (thermostatic mixing valve) certificates on the international Kiwa Group stand at the ISH Water and Energy trade show in Frankfurt.
David Jay, Business Manager at Kiwa Watertec in South Wales, explains: “It’s a really robust scheme, offering an alternative approach to gaining approval for thermostatic mixing valves…I’m delighted to see so much interest”.
Kiwa’s TMV Scheme includes initial product testing, manufacturing process checking, as well as an ongoing testing program over the lifetime of the product.
