Application
Elastic seat seal gate valves are widely used as regulating and closing devices on fluid pipelines such as tap water, hot water, sewage, construction, petroleum, chemical industry, food, medicine, light textile, electric power, ships, gold treatment and energy systems. It has the characteristics of sensitivity, reliability and convenient installation.
Characteristic
• The use of elastic gate to produce trace deformation of compensation, to achieve good sealing effect;
• With light switch, reliable seal, long service life and other significant advantages;
• Stem nut and gate two body structure, no stuck phenomenon; Through channel, no discharge left concave cavity; The valve stem seal is o-shaped sealing ring;
• Excellent anti-corrosion properties, the shell inside and outside the surface of epoxy resin spraying, if necessary, the inner surface lined with enamel;
• Reliable sanitary epoxy resin in line with sanitary standards, and the whole gate is coated with rubber in line with sanitary inspection;
• Stem, stem nut and other parts are made of stainless steel or bronze and other materials that are not corroded by water;
• Gate valves can be operated by lever, handwheel, electric and pneumatic.
