SchuF Worldwide Group For over 100 years SchuF valves have stood for innovation and quality at the highest level. SchuF invented the first bottom outlet valve over 100 years ago, and today, the SchuF Group offers flush-mounted valves with a disc or piston design in various materials and classes, with many options. These valves are custom-manufactured to exact tolerances for use in specialised processes with often challenging operating conditions. SchuF Valves can be found in standard and severe service applications in the Chemical, Polymer, Pharma, Oil, Gas, Offshore and Refining...

Customer-driven design Flush-Mounted Valves- Features and Options Flush-Mounted Custom Seats SchuF will use the exact nozzle/piping dimensions to design custom valve seats to eliminate dead-space. Material Choice Cast-steel, stainless steel, nickel-based alloys including Hastelloy®, Incolloy®, Inconel®, Monel®, plus Titanium, Zirconium and many others. Valve lining can be PTFE, PFA or glass. Hardface options include Stelliting, Tungsten Carbide, ceramic, etc. Options include electric, pneumatic, hydraulic or manual operation, possibly in combination.

Disc Flush-Mounted Drain Valves SchuF disc valves are available in both Disc Rising and Disc Lowering variants, each with advantages in certain vessel/pipeline installation situations. Both types are also suitable for use as injection valves. Type 25 (Disc Rising) valves utilise the vessel pressure forces to help seal the valve in a flow-toclose design, thereby requiring smaller actuator forces to achieve a seal, especially in high-pressure systems. Type 25 valves also provide a crust-breaking function. Type 24 (Disc Lowering) valves operate in a flowto-open arrangement, and can be mounted...

Disc Flush-Mounted Drain Valves Disc Bottom Outlet Valves are ideal when addressing the following process requirements: ■ Lower stem-sealing forces are required ■ Low initial and maintenance costs are a factor ■ There are space restrictions underneath the reactor ■ Absolute tight shut-off to atmosphere is necessary (bellows-seal) ■ The valve size is above 8“/DN200 ■ Flushing of the valve body cavity during reaction is desirable ■ The valve is for lethal service ■ Short travel is advantageous Selecting the ideal Disc Bottom Outlet Valve Type ■ Is pressure helping to close the valve? ■ Is...

Disc Flush-Mounted Drain Valves SchuF is the inventor (in 1923) of the Disc Bottom Outlet Valve. These valves are ideal for draining tanks, reactors or pipelines, and are widely used in the pharmaceutical, fine chemical, biochemical, and mineral-refining industries. Key Features D ■ ead-space-free nozzle connection ■ pace-and weight-saving valve design due to shortS stroke operation, ■ Smaller, faster, lighter actuation ■ Zero leakage-to-atmosphere options ■ Options for fire-safe, crust-breaking, clean-in-place, sensors / P.A.T. (see SchuF Pharma brochure) and integral sampling available...

Disc Flush-Mounted Drain Valves- Features and Options Seal to Atmosphere Minimising or even eliminating fugitive emissions to atmosphere is a highly important aspect of valve performance. All SchuF valves can be supplied with a number of different arrangements to suit any customer requirements in this area. Standard Packing Bellows Seal Live-Loaded Packing Packing rings are compressed using a stuffing-box gland, which can be regularly tightened as required using standard studs/nuts This utilises an expanding/contracting bellows (PTFE shown here; metal also available) and incorporates a...

Disc Flush-Mounted Drain Valves- Special Options Lined Valves SchuF flush-mounted disc valves see extensive service in the bulk pharmaceutical and fine chemical industries. The Type 25 bottom-outlet valve with lining in glass, PTFE/PFA, tantalum, or other materials such as rubber, provides the ideal solution when customers require a flush-mounted, custom fitted valve with high corrosion resistance and complete operational reliability in order to maximise their system’s high-level functionality. Bespoke design requirements can be incorporated into each valve alongside tried and tested...
