RAM Bottom Outlet Valve
Ram Valves are used when full flow is essential to drain reactors and vessels, flush pipelines, inject media such as kill gases and catalysts and take large samples. SchuF Fetterolf offers the widest range of design and sealing arrangements for every application. Please contact one of our offices or local agents for advice.
Valve Seal to Atmosphere Options
Packing rings are tightened with the stuffing-box gland to give a radial seal to atmosphere around the ram. Packing rings can be ordered in PTFE or graphite (high temperature / FIRE SAFE) forms or even in a mix of both. More specialized packing arrangements are available, including Chevron/PTFE and Garlock/Graphite sealing sets.
Valve Materials of Construction
SchuF Fetterolf valves are available in many different materials to suit the customer and the process. The valve bodies and trim can be supplied in stainless steel, carbon steel, Hastelloy, Inconel, nickel or titanium. Internal lining can be supplied in PTFE, PFA, rubber or glass. Surfaces can also be ordered with specific coating: Stelliting, titanium-nitriding, Canadizing, Kolsterising, chrome-plating and others.
Ram-Seal® Valve Sealing to Atmosphere – Options
Ram-Seal® valves use packing rings for sealing to atmosphere. The packing rings are tightened using the stuffing-box gland to give a radial seal to atmosphere around the ram. Packing rings can be ordered in TVE/KEV or Graphite (suitable for high temperature or FIRE SAFE operation) or even in a mix of both. More specialized packing arrangements are available, including Chevron PTFE or Garlock graphite sealing sets.
Rod-Seal® Valve Sealing to Atmosphere – Super Closure
Rod-Seal® valves offer the unique Super Closure feature. A cross-head component, mounted at the end of the ram, compresses the stuffing-box gland only when the valve is fully closed. Thus, all the forces of actuation are carried by the guide bush to the packing rings and the radial seal at the top of the valve. This increased closing power ensures a tight shut-off to the process and the atmosphere. This sealing force eases when opening the valve.
