      ARV/SG Combined Check Valve and Bulls Eye Sight Glass

      The ARV/SG is a Bulls Eye Sight Glass incorporating a fully functioning ball check valve. Under normal flow conditions the valves solid PTFE ball is pushed away from it’s seat and fluid flows through the valve, if the flow reverses the ball is pushed firmly back into it’s seat and prevents flow through the valve. Along with the process stream, the state of the check valve and hence flow direction can be easily seen through the windows.

      The ARV/SG has 2 borosilicate glass windows. The body is PFA lined ductile iron body with stainless steel fasteners. The PFA liner is securely locked in to its housing with T slots. Within the body, virgin PTFE internals are used to guide the ball. The use of PTFE and PFA means that it has near universal process corrosion resistance.
