The FIP VKD and VKR models are high-quality ball valves with advanced technology. The ball valves are practically identical, meaning that both the valves and the parts are interchangeable. The only difference between the two models in the internal ball: the VKD model has a movable while the revolutionary design of the VKR model allows a linear control of the capacity. Pneumatic or electric drives are connected by means of a special PowerQuick adapter. The PowerQuick is made of a PP engineering polymer (housing) and stainless steel (shaft). The automatically actuated ball valves are interchangeable with manually actuated VKD models.. Characteristics of VKD ball valve Broad range, including straight and 3-way models DUAL BLOCK system; locking system that ensures that the glands remain in position Characteristics of VKR ball valve The same as for the VKD valve, but then with a practically linear characteristic in 90° rotation For the characteristics of the electric and pneumatic drive, ...
