Application The butterfly swing check valves are self-acting and fast-closing valves which prevent a working medium from flowing back in a pipeline. They are used in order to prevent from backflow the pumps, fans etc. The check valve is not a shut-off valve. Working medium Water, air, steam and other non-aggressive liquids and gases. The fluid flow direction may be only from one side of the valve. The fluid flow direction is marked with an arrow on the valve body. Working temperature Service temperature depends on the material of seals. - 46°C up to 300 °C Technical description The valve disc, eccentrically embedded, rotates inside a flanged end fabricated body. The shaft is clamped in the self-lubricated friction bearings. Outside the valve on the end of the shaft there is the lever with counterweight. Operation The swing check valves are automatic, quick-acting valves. Movement of the disc is controlled by the flowing fluid. Testing The butterfly swing check valves are tested for strength and leakage, functionality and tightness acc. to EN 12 266 section 1, leakage grade is D (grade B on request) or acc. to API 598. Connection to piping flanged ends acc. to EN 1092-1, EN 1759-1 or GOST 12815-80 face to face dimension acc. to EN 558 welded ends acc. to EN 12 627 face to face dimension acc. to EN 12 982
TYPE L10.6
Application
Extraction swing check valves are special valves used to prevent the back flow of the service fluid in extraction and bleed lines.
Working medium s team
Maximum service temperature:
to +530 °C to DN 900, NPS 36
Technical description
Bodies of extraction swing check valves L10.6 are made of forged, cast or welded semi-finished products depending on parameters
specified by the customer. The seat ring is pressed into the body and secured by welding. Its seating surface is hard-faced. The shaft is
carried in plain bearings and holds the disc arm with the disc which is secured by a pin. The seating surfaces of the seat and the disc
have a plane contact surface. The welded design of the extraction swing check valves meets the requirements of EN ISO 15614-1, PED
2014/68/EC or, if required by the customer, ASME CODE, Section IX.
Construction types
f orged - to DN 350, NPS 14 cast - above DN 350, NPS 14 welded - from DN 200, NPS 8 to DN 1000, NPS 40
Operation
Connection to the piping
Self-acting, the safe closing of the disc is realized by the ancillary actuator (pneumatic, hydraulic actuator). Actuator type as specified
by the customer.
Possible valve equipment h and lever e lectric position sensor
Testing
The valves are tested in accordance with:
E N 12266-1 / ISO 5208 A PI 598 A SME B16.34
Forged design with pneumatic actuator
fl anged ends according to EN 1092-1, ASME B16.5, ASME B16.47 w elding ends according to EN 12627, ASME B16.25
Face-to-face and end-to-end dimensions according to manufacturer’s specification.
Installation
The extraction check valves L10.6 may be installed into both horizontal and vertical pipings. When installing the extraction valve
into a vertical piping, the fluid has to flow from under the disc (to lift
it up), when installing it into a horizontal piping, the cover must be above the valve body (±10°).
Advantages
Possibility of use for high pressures PN 160, PN 250 and high temperatures exceeding 500 °C.
