Butterfly valve seat

Material: Polytetrafluoroethylene (PTFE) + EPDM (EPDM)

Specifications: DN50—DN250 (2 inches—10 inches)

Link form: folder type

Type: straight-through

Standard: American Standard (also can be customized according to customer drawings)

Applicable medium: oil, gas, water corrosion;

Scope of application: valve pipelines, chemical pipelines, printing and dyeing, ships, food, beverages, medicine

Features: high temperature resistance, low temperature resistance, acid and alkali resistance, abrasion resistance, oil resistance, corrosion resistance, etc., labor-saving installation, repeated pressure, good resilience, no leakage, strong and durable;

Applicable temperature range: It can be used for a long time under the temperature condition of 120℃-160℃;

Note: Polytetrafluoroethylene (PTFE): It is a fluoroplastic. This material has strong resistance to acids, alkalis, and various organic solvents. At the same time, the material is resistant to high temperatures and can be continuous at a temperature of 260°C When used, the unique properties of PTFE make it widely used in industrial and marine operations such as chemical industry, petroleum, textile, food, papermaking, medicine, electronics and machinery.

EPDM (EPDM): Compared with other general-purpose rubbers, EPDM has great advantages.
1. Its cost performance is very high. Among the commonly used rubbers, EPDM has the lightest raw rubber density;
2. The EPDM material is resistant to aging, sun exposure, heat resistance, moisture resistance, and radiation resistance. It is suitable for weak acid and weak alkali media and has good insulation properties.
3. Applicable temperature range: as low as -40℃-60℃, it can be used for a long time at a temperature of 130℃.

Advantage:
1. We compound the two materials of PTFE and EPDM together. Compared with valve seats of pure rubber and other materials, this is more wear-resistant and durable;
2. Everyone knows that the biggest problem of PTFE and EPDM compounding together is that it will cause degumming during use, and the biggest advantage of our factory's production of this product is never degumming;
