    Noshok® 204-EMFS is a multiport needle valve part of the 200 series family.  They are designed to allow pressure to be bled off without disturbing the permanent piping installation. Their multiport design reduces the number of gauge and other instrument connections to permanent piping installations and decreases possible leak paths. The 200 series has a blow-out proof stem that provides a secondary stem seal in the fully open position.  All stems are 316 stainless steel and all stem threads are rolled for strength and ease of operation. Other features include a one-piece bonnet with a metal-to-metal seal to the valve body below the bonnet threads and a slotted spring pin to prevent accidental loosening.
