Products Details
Stainless steel flange butterfly valve with pneumatic actuator
JRVAL specialized in stainless steel material flange type butterfly valve production, which have been focusing on stainless steel material butterfly valve production over 15 years, with over 300 customers from home and aborad.
 
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;
