1 OCTOBER 8. kysimply Unique Single Seat lfa Laval Unique SSV Tangential Concept The Unique Single Seat Tangential valve meets the highest demands of your process in terms of hygiene and safety. Built on the well-proven Unique SSV platform it offers complete drainability of the valve body on horizontally mounted valves. It can be configured as a shut-off valve with two (2) or three (3) ports or as a change-over valve with three (3) to five (5) ports. Working principle The valve is a pneumatic seat valve in a hygienic and modular design remote-controlled by means of compressed air. It has few and simple moveable parts which results in a very reliable valve and low maintenance cost. Standard design TheUniqueSSV Tangential valve comes in a one or two body configuration. With its module built structure it is designed for flexibility and easy customization through the electronic configurator. The valve features an optimized life span of the seals through a defined compression design. The actuator is connected to the valve body using a yoke and all components are assembled with clamp rings. TECHNICL.

For the diagrams the following applies: Medium: Water ( C) Measurement: In accordance with VDI2173 ressure drop can also be calculated in nytime configurator. ressure drop can also be calculated with the following formula: Q=Kvx p Where Q=Flowinm 3 /h. Kv = m 3 /h at a pressure drop of 1 bar (see table above). p=ressuredrop in bar over the valve. Where Q=Flowinm 3 /h. Kv = m 3 /h at a pressure drop of 1 bar (see table above). p = ressure drop in bar over the valve. 2.5" shut-off valve, where Kv = 111 (See table above). Q=Kvx p = 111 x p bar (This is approx. the same pressure drop by reading the y-axis above)
