Kinds Of Butterfly Valve Rubber Seat For Resilient Seated Butterfly Valves

kinds of seat valve for resilient seated butterfly valves

The rubber seats of all categories of midline values produced by SML are made of materials with good elasticity, excellent pressure variation, stable sizes, small torsion resistance, good sealing and material performance.

Size range: DN50(2inches) - DN1350(54 inches).

Basic characteristics of material NR

1. Unsaturated rubber, active chemical properties, can carry out addition and cyclization reaction, and sulfur, oxygen and other reactions, easy to react.

2. Non-polar rubber, none oil resistance.

3. Crystalline rubber has self-reinforcing properties and high elasticity.

4. Become glass state under -70 degrees.

5. With good comprehensive performance: high tensile strength, high elongation, low heat generation.

6. Good air permeability and electrical insulation.

8. Anti-aging and returning performance is poor, anti-aging system and vulcanization system and anti-reversion system should be considered when manufacturing products.

9. Use in tires: mainly used for tread of heavy-duty tires, truck tires and light trucks..

Certificates obtained:

IATF16949 quality management system, certififies include WRAS, EC1935, ACS, NSF61/372, KTW, W270, FDA, DVGW, EN681, RoHS, REACH... for the needs of different countries.

Heat / Cold Resistance of different rubbers

With 20 years of operating experience, Suzhou Meilong Rubber & Plastic Products Co., Ltd, with its self-developed formula of the rubbers, has obtained the German KTW, W270, British WRAS, US NSF61/372, French ACS and other water treatment industry international certifications, as well as the FDA and domestic drinking water related regulations.

Our main production lines are: all kinds of rubber valve seat for concentric butterfly valve, including pure rubber seat and with reinforcing material valve seat, size range from 1.5 inch - 54 inch. Also resilient valve seat for the gate valve, centerline valve body hanging glue, rubber disc for the check valve, O-ring, rubber disc plate, flange gasket, and rubber sealing for all kinds of valves.

Applicable mediums are chemical, metallurgy, tap water, purified water, sea water, sewage and so on. We select the rubber according to the application media, working temperature and the wear-resistant requirements.
