Bettis® Switching Relays are pneumatic/hydraulic poppet style switching devices — manual or pilot operated — for use with high or low pressure control applications. In pneumatic service, they can operate with high pressure gas to 1500 psig, or to 150 psig in low pressure service. The switching relays are also available as hydraulic models, operating to a maximum of 2160 psig. The Bettis® relays are available as 3-way and 4-way 2-position bodies with a range of switching options including pneumatic or hydraulic pilot, mechanical and manual lever.
