Description
The Kofloc Model EX-550 Series is engineered to meet the stringent “cleanliness” requirements of the modern electronics and specialty chemical industries. The defining characteristic of the EX-550 is its all-metal seal construction. Unlike standard controllers that use FKM or NBR O-rings, the EX-550 features a weldless SUS316L body with metal seals, which eliminates the risk of contamination from plasticizers and prevents the absorption/permeation of moisture and atmospheric gases
