A bras valve is a sound choice. However so you know, the 150 psi rating on any valve does not mean it will explode at 151 psi. All they are implying is that is the valve recommended maximum pressure, I however am like your self in this matter. Why run the risk? Well if it were me, I would go with Rain-Bird 200 psi valve such as the PEB series. They are far less expensive as the brass and parts are generally more available. But by all means, go with what is more predominant in your area. If you have to repair the valve or replace it for any reason, it will be easier to find the parts. A few other good choices in 200 psi valves are Weathermatic Silver Bullet, Nelson 9500 series valve, Hunter ICV. If I am not mistaken all offer pressure regulation, but only a few may offer both globe and angle configuration.
