Lift Plug Valves
Poyam Valve: Featured Product #1
Body available in standard materials and special alloys
Seating surfaces on both body and plug are precision ground to a mirror-like finish which forms an excellent metal-to-metal seal.
Because the body seats are raised and the plug seals peripherally, they are protected from the flow material in both the open and closed position. This greatly increases the life of the valve.
No lubrication is required inside the body of on the plug for seat sealing, plug rotation, or to prevent sticking. This eliminates the time and expense which might otherwise be required for lubrication. It also means there is no foreign matter in the valve (i.e. no lubricant) to contaminate the flow material.
The ability to keep the sealing surfaces clean by means of flushing ensures that erosion during the operation of the valve and closure on particles cannot take place.
Plugs are available with 70% and 100% port openings
