• Overall rubber-covered valve core
The valve core is a Ductalloy frame, both outside and inside are integrally covered with high performance rubber with the latest sulfurization know-how, closely and securely, leaving an extremely good sealing elasticity and a null leak.
• Flat bottom type seat ring
The seat ring with the conventional gate valve usually is a concave type, it causes the fluid resistance increased and the weld-drugs, stone, muddy sand etc. impurities easily piled up and so adverse to sealing and flowing. While for the elastic seat seal gate valve, the bottom is full-flowing-area through-way designed, having impurities uneasily piled up and ensuring a reliable seal, smooth fluid without resistance and a lean water quality.
• Three turns of ¡°O¡±-type rubber shaft seal
Compared with the packing seal structure of the conventional gate valve, the design of three turns of ¡°O¡±-type seal feature close sealing, greatly reduced frictional resistance and environmental protection. The ¡°O¡±-type seal ring can be easily replaced with the valve at any opening, the pressure available and the water not cut off.
• Anti-corrosion
Both internal and external surfaces of the body are coated with epoxy resin powder and the internal parts are made of stainless steel or copper alloy to prevent rust and corrosion by the fluid and have it applicable in a sewage system and outdoor and underground etc. severe places.
• Helpful for living water
Because the inside of the body is coated with non-toxic epoxy resin and both internal and external surfaces of the valve core are covered with rubber, so there would be no rusted water or corrosion and it is applicable for the living water system, food and medicine trades. |
