    Thrust Equation

    You need to talk to the valve manufacturer and find out what their thrust requirement for the valve is at the specific line pressure. Once you know this you can size a linear actuator based on the pneumatic pressure available. The pneumatic actuator will generally be much faster in operation...

    When is a certificate 3.1b?

    In my experience the certifcate must state 3.1.b. If it does not, it can be very dificult, most of the time impossible, to have the paperwork accepted by third party inspection authorities.

    Welding Valves

    I assume that when you say welding you are referring to socket weld flanged valves. If this is the case then it is normal practice to remove the centre section of the valve and weld the flanges to the pipe. When welding is complete and the pipe/flange assembly cooled, the valve centre section...
