THE COMPANY



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 1.250º 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.

The mounting flange for the actuation and the free shaft end is made following ISO 5211 / DIN 3327; and the types of actuation are:

 1.- Manual handle.
 2.- Wormgear.
 3.- Double acting pneumatic actuator on-off.
 4.- Single acting pneumatic actuator on-off.
      (springs to close / springs to open). 
 5.- Double acting pneumatic actuator for regulation (4-20 mA / 3-15 psi).
 6.- Single acting pneumatic actuator for regulation (4-20 mA / 3-15 psi).
      (springs to close / springs to open).
 7.- Double acting pneumatic cylinder on-off.
 8.- Double acting pneumatic cylinder for regulation (4-20 mA / 3-15 psi).
 9.- Pneumatic actuator membrane for regulation 3-15 psi.
10.- Electric actuator on-off.
11.- Electric actuator for regulation 4-20 mA.
12.- Electric actuator linear for proportional regulation 4-20 mA.
       (incl. linkage).
