Valve covers are a great way to insulate screwed valves. They fit perfectly around screwed valves and preventing heat loss and also protecting the valves from any damage, dirt and impurities. In our expert option, valve jackets are the best way to insulate screwed valves and here's why:

  • Thermal insulation: Valve jackets that we supply are made with superior quality silicone glass fibre cloth. The cloth contains 50mm mineral wool, which is known for their supreme insulation. 

In addition, valve covers have pull cords and velcro straps, which not only makes them easy to install but also ensures a snug fit around the valves, so there is no space for a heat loss. These valve jackets are hand-made to ensure quality and efficiency. 

  • Safer Workplace: Valve covers help protect your workforce from contact with the hot surface of the screwed valve, hence improving workplace safety. They also protect screwed valves from condensation or seating. As a result, water does not drip which prevents the formation of tiny water pools in the workplace, leading to accidental slips or mishaps. 
  • Easy Maintenance: Valve covers come with velcro straps and pull cords that ensure the s snug fit around screwed valves. Hence there are no gaps left in the insulation, resulting in a more energy-efficient building. This also reduces installation time by half. Plus valve covers are not lost or harmed in any way when each time you remove them from the valves, for maintenance, unlike hard, traditional insulation. 
  • Protection from moisture and damage:  The external valve covers are made with PVC cloth on the outer and silicone glass cloth on the inner side of the cover. The PVC cloth makes these valve jackets waterproof and more resilient to damaging external conditions.
