Are all the isolation valves straight ?

[Raks]

To put a isolation valve over the floor level for a pipe running under,  is there any "bottom only connection" type valves? 

Let me explain what I meant:

Right now to add a isolation valve:

 straight up pipe to floor level + isolation valve + short straight + U bend connection + straight back to the pipe under floor.

I just wonder if there are special valves with two connections at the buttom one for IN one for OUT so nice tidy two pipe connection without extra bends and soldering.

Surestop stopcock under the floor with remote "switch " on the wall above?

this might work for water but I need for gas as well.

(but I feel better with a mechanically more reliable lever ball valve)
