VB-20
3-Pieces Forged Ball Valve
Working Pressures: 100 | 200 bar (1500 | 2900 PSI)

Tecval VB-20 3-Pieces Ball Valve is a Forged Body design. The forging process reduces the surface porosity and closes up internal cavities. The result is mechanical stronger and more durable product, especially suitable for working in high corrosive environment. They are manufactured under ASME B16.34.

Compensation springs on packing stem.
 
Three pieces to allow a full disassembling.
 
Easy cleaning and maintenance.
 
No ejectable stem design.
 
316 SS handle to reduce the risk of corrosion.
 
100% tested.

Ordering information

References are formed by three parts:

 Valve Code  Look for it in the order codes chart on the previous page.
 Option/s  If required, add the code/s from the options section on the previous page (in alphabetical order).
 Material  Look for the code on the materials chart.

Example of ball valve VB-20 with two options: 

Ball valve VB-20 1"NPT (SB) Superduplex with handle safety lockout and FPM seals:
 6102   VI   W   AS  The reference required to place the order is 6102VIWAS .

 

   
Actuators

Upon request, ball valves VB-20 can be delivered with:

  • Pneumatic actuators: either double acting (DA) or spring return (SR). 
  • Electrical actuators: of 24V, 115V and 230V can also be assembled.

For detailed information please consult the sections on Electric and Pneumatic Actuators. 


Tests

100% valves are tested in accordance to API STANDARD 598, each valve is tested to check the leakage in the seats and packing. However they can also be tested under other standards such as EN12266. Upon request, the corresponding materials (EN10204 3.1) and test certificates can be delivered with the valve.


Maintenance

Valves with long no-working period may have a harder initial operating torque. Are designed to be operated in a fully open or fully closed position.
