Suttner ST-230 Adjustable Safety Relief Valve is used to control or limit the pressure on your machine which can build up by a process upset, instrument or equipment failure. It boasts a forged brass housing, stainless steel ball and valve seat. It also includes special seals for maximum heat and chemical resistance. The valve member rides on elastomeric cushion, eliminating metal to metal contact, a common cause of regulator failure.
