Product performance&structure
1, Working pressure: 1.6Mpa
2, Inspection standard: API598 DIN3230
3, Suitable Flange standard: DIN2501 PN10/16, BS4504 PN10/16, BS10 TABLED/E, JIS2220 10K/16K, ANSI125/150
4, Face to face: ANSI125/150, DIN3203 K3-1999, ISO5752-1982
5, Working temperature: EPDM -10° C~+120° C, NBR -10° C~+80° C, VITON -23° C~+150° C
This valve is installed in pipeline system as a medium against-flow protecting equipment
PN Nominal Pressure: 1.6Mba
Sealing Test Pressure: 1.76Mba
Strength Test Pressure: 2.4Mba
Suitable temperature: -20~135
Medium: Fresh water, Sea water, Waste water, Food stuff, Steam, All kinds of oils, All kinds of acid and alkali liquid, etc.
Usage:
They are used for pipe of transporting water with such medium as water sewage and seawater. It can avoid media flowing backwards and prevent damaging water hammer, guarantee the safety using of pipes.
Main Features:
Dongsheng Dual Flap Wafer check valve is designed to operate with the minimum of flow restriction.
The twin spring loaded half disc operate with the pipeline flow and reseal back against the rubber disc seating providing a positive shut off against any back flow. The resilient seating prevent a slamming action.
Check Valves offer greater flexibility and low cost in most piping systems and moreover, of its light weight, it is so convenient to install and has smaller face to face dimension than conventional Swing check valve.
These valves can be supplied to match the international standards of flange (DIN, ANSI, JIS & BS).
DongSheng check valves when compared with order traditional isolating valve such as Swing Check Valve offer the following advantages:
Low purchase cost
Compact design
Non-slam principle of operation
Light weight
Easy installation
Good flow characteristic and less pressure drop
Suitable for horizontal and vertical up flow
Typical Applications:
Heating air-conditioning pipe lines
High frequency lines
Fire extinguishing system
Vessel pipelines
Iron and steel industry
Mineral, oil industry
Wood working, pulp and paper industry
Textile industry
Water and condensate lines
