VALVULAS JOLA
DESIGN AND MANUFACTURE OF VALVES FOR HIGH TEMPERATURES
VALVULAS JOLA designs and manufactures different types of valves for high temperatures since 1983; when we started our activity.
Our manufacturing program is:
- Butterfly valves for high temperatures.
- Dampers for high temperatures.
- 3-way diverters for high temperatures.
Our valves are manufactured in all sizes, for different mounting types (wafer, lug, flanged) and in different shapes (circular, rectangular, square); being designed for working with temperatures up to 1.450º C.
The mounting flanges are: DIN PN6, DIN PN10, ANSI 150#, ANSI 300#, JIS 5K, JIS 10K, . . . etc.
The valves are manufactured in casting designs and depending on the application, the type of material is chosen: Grey Cast Iron GG-30, Nodular Cast Iron GGG-40, Alloyed Cast Iron GGG-HS-40, Cast Carbon Steel ASTM-A-216-WCB, Cast Stainless Steel ASTM-A-351-CF8M, Refractory Cast Steel ASTM-297-HK, . . . etc.
All valves have a number mark for the casting identification, being certified in an individual valve certification.
