May need more details, such as the valve type, size, application, etc.

Is this the same as rising stem valve?

I don't understand, OP say's "Our company developing valves which require non-rotating single piece stem."
But cannot find a feasible design, and looking for a design all over.
So is the OP's company developing a valve or looking to procure a valve?
As stated in the earlier response, more info helps.

ok, our company wants to develop piston globe valves which require single piece non rotating stem to lift piston. all i want to know to know ideas to make single piece non rotating stem which can let piston translate.

Can you draw our sketch this.

A "piston globe valve" sounds like a choke valve or plug and cage valve to me.

Why can't you just machine it or cast it?



Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

It would obviously be helpful to know what sort of globe valve it is, isolation, control or choke...

But equally most product standards have generic images in the back of them these days, surely there is a target market with their own requirements on conformity to product standards??

Click to expand...

It sounds that it's to mount a piston actuator on top of valve, and make it move "up and down" direction, i.e. vertical movement, to control the valve, instead of "horizontal" movement. And, the piston cylinder is to be seal with packing on the valve body.

Is this design a business driven or the operational requirement?
