D671X-16 Wafer Pneumatic Butterfly Valve Description

Carbon steel wafer butterfly valve with pneumatic actuator

JRVAL was founded in 2004, has been focusing on carbon steel material butterfly valve production over 15 years, with hundreds of customers from both home and abroad.

Products featurers:

1) The valve stem bearing use "copper sleeve", which with good wear and corrosion resistance. Although cost is 50% higher than other materials, prolong the service life by 60-70%;

2) Rubber seat contains over 50% rubber, with stable resilience and tension. Although the cost is 30% higher than that of similar products in the market, its service life can be extended by 1-2 years; valve seat option with PTFE, NBR, EPDM, FKM etc.

3) Material of worm gear includes gray iron, ductile iron, stainless steel, aluminum alloy, etc;

4) Pneumatic actuators includes 2 type: double acting and Spring return; Double Action pneumatic actuators with double cylinder structure, including GT and AW Models; Spring Return pneumatic actuators with single cylinder structure, including GT, AT and AW Models.

5) Cost of Double action pneumatic actuator is lower than Spring return actuator;
