Available with either a brass or Stainless Steel body, the rugged body provides for long life. With four different NPT pipe sizes available*, installation is simple. A soft resilient EPDM seat provides for quiet opening and closing. This, combined with the internal spring, prevents “chatter” when the valve is operating.
