Characteristics
The swing check valve adopts EPDM soft seal for reliable tight shutoff and anti-backflow performance. Swing disc structure brings large flow area and low pressure loss, reducing water hammer impact. Widely used in water supply, fire fighting, HVAC and general clean fluid pipelines to prevent medium reverse flow automatically.
Advantages
1.GGG40 ductile iron owns high toughness and impact resistance. Epoxy coating avoids rust, stable pressure bearing and longer service life.
2.EPDM rubber seal features great elasticity and aging resistance, tightly fitting the seat to achieve reliable tight shutoff under variable pressure..
3.Swing disc design provides large flow passage and low flow resistance, effectively reducing water hammer to protect pipeline equipment.
Packing
Standard export wooden case packaging
Application Scenarios
This non-return valve swing type is widely used in municipal water supply pipelines, HVAC circulating water, fire protection systems, sewage treatment, residential irrigation and heat exchange projects.
