2219 Series – Severe Service Needle Valves
The new Hoke 2219 Needle Valve is an excellent choice for many steam- and_x000d_
severe service applications. Grafoil packing below the stem threads provides_x000d_
exceptional service at temperatures up to +1000° F (+538° C). The nonrotating_x000d_
316 stainless steel stem tip prevents galling.
