Elastomer Butterfly Valves
Valves known as butterfly valves are designed to regulate or shut off the flow of a medium. In the GTM Process Valves offer, we have wide range of elastomeric valves characterized by high-quality construction. They are distinguished primarily by the elastomeric sleeve, which ensures 100% sealing in both directions. The most commonly used seals are EPDM, NBR, and FKM. We provide models in various diameters – from DN32 up to even DN1200. We warmly invite you to explore our range of elastomeric butterfly valves, which will meet the expectations of every customer and can be applied in many different installations.

Elastomer Butterfly Valve
The elastomer butterfly valve is a type of valve used for shutting off or regulating flow. In our range, there are numerous diverse models that enable efficient control of medium flow. Available within GTM Process Valves’ assortment, elastomer butterfly valves are equipped with a centrally mounted disc made of stainless steel or ductile iron GGG40. This material combination ensures maximum disc durability, making them suitable not only for water treatment but also sewage treatment, as well as chemical and petrochemical mediums.
It’s worth noting that our product line includes elastomer butterfly valves utilizing four types of actuators. In the GTM Process Valves range, you can find models operated by manual levers, worm gearboxes, pneumatic actuators, and electric actuators. All these valves are CE marked and have various certifications (such as PZH or DVGW). Such designs will meet the expectations of all customers, regardless of the specific industry in which they are to be utilized.
