The Primet mini-bellows valve, PSBV series, uses the machine-processed SUS316L for the main body. In addition, its bellows are also made of SUS316L and the valve structure is designed to be hermetically sealed. It is compatible with four types of coupling (metal seal, doble ferrule, weld and union).
