Nason Valve - Looking for a different, more reliable brand.

Hello
I was wondering if there is anyone here who has some experience with this Nason Valve? Seems like my propane company is having to replace them too often. When this value stops working, our freightliners will not go into gear. It seems the seals on these start leaking over time. What I'm really looking for are some other (more reliable) brands. We've had to replace hundreds according to my supervisor.

Note: The function of this value is to keep the truck from moving in the event that a driver forgets to close the internals and hook the hose filler back onto the arm in the back of the truck.

Advanced Thanks
Mike.

 

Yes, I just got an email from Nason company. They want me to send them the old part to see what's going on. So I'm going to do that. We've had to replace a ridiculous amount of these.
