Wafer Worm Gear EPDM Seat Butterfly Valve D371-16 Description

Carbon steel wafer butterfly valve with worm gear operation

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.

Product Featurers:

1. Main parts of valve body and disc are cast and machined by Jiangrui itself, with professional capacity to produce WCB carbon steel butterfly valve, higher technical LCC ultra-low temperature carbon steel material, which is core technical of Jiangrui.

2. The valve body design is refer to the drawing size of "Tanggu watts" butterfly valve, which is a leading enterprise in China, and strictly follow the international standards. Jiangrui maintained long-term cooperation with many renowned valve enterprises such as Tanggu Jinbin valve, Beijing Dingruite... etc.

3. Due to the high market recognition, many valve producers imitate us, although the appearance of the body is basically the same, the thickness of the outer circle, upper flange and neck of Jiangrui valves are 3-5mm thicker than the imitated products, weight of valve is 20% - 30% higher, the pressure bearing capacity  is 20% higher than the imitated products also.

4) Based on different valve size and differnet opening torque, worm gear includes small torque, medium torque, large torque, single gear, double gear, tripple-gear etc;

5) With Different settings can be customerized, such as: Worm gear+signal, worm gear+indicator, worm gear+solenoid, worm gear+bracket, worm gear+ Siemens electric controller, worm gear+ indicator light and other configurations are avialable.
