Single seat valves for all range of application Right angle valve Inclined-seat valve Right angle valve with manual handle Change-over valve two-part valve body alternatively one-part valve body Double seal valve DD Bottom seat valve Overflow valve ÜS optional manual operation Piggable double seal valve N4 Overflow valve E8 with T-body Safety valve SH TÜV approved

Hygienic overflow valve ÜS Hygienic overflow valve E8 protect your process and equipment for a safe pressure reduction Rieger overflow valves type ÜS open when the set pressure is reached to prevent excess pressure in piping or systems. These are not safety valves. If safety valves are required, we recommend our TÜV approved safety valves type SH (see page 10). The Rieger overflow right angle valve E8 is a combination of right angle and overflow design. The desired pressure is adjustable, with a valve stroke as high as possible. Unlike an overflow valve this valve can be opened up to 100% –...

Hygienic safety valve SH Hygienic regulating valve E with TÜV-approval for gas and steam providing product control at desired flows The Rieger safety valve Type SH prevents excess pressure of gaseous media in pipelines and vessels. Rieger regulating (control) valves are designed to meet the highest process demands of hygiene and safety. The set pressure is always higher than the operating pressure. As soon as the pressure is reached, the valve opens against the force of the spring. The pressure excess is relieved as soon as the pressure is 10% higher than the set pressure. Ideal...

Hygienic double seal valve DD Hygienic double seal valve N4 a safe media separation Rieger double seal valves are used for reliable separation of product from cleaning agent. The leakage space is situated between the separating gaskets. The leakage fluid flows through two leakage valves. The RIEGER double seal valve piggable version N4 allows potential savings for products, water and cleaning chemicals in combination with a pigging station. Reduced environmental pollution plus additional product savings shorten the Return On Investment (ROI) and amortization period. / valve body from solid...

Hygienic mix proof valve N1 reliable separation of liquids Valve structure / valve body from solid bar / radial sealing of both valve seats / balanced valve disks Easy of servicing / only 4 seals in product space / change of seals without special tools / service possible without compressed air / minimal downtime / light: valve DN 100 (4”) only weighs 35 kg (77 lbs) valve matrix Product protection / stroking without product loss / safe media separation of both product lines / closing force up to 10 bar (145 psi) / water-hammer safe up to 30 bar (435 psi) / CIP-cleaning and SIP-sterilization...

Hygienic mix proof change-over valve N3 Hygienic mix proof bottom seat change-over N9 Valve structure / based on the N1 technology with additional change-over function / two-part valve body – lower body turnable / optional three-part valve body – all bodies turnable / upper valve seat can be stroked upwards and downwards Rieger offers mix proof bottom seat valves where additionally the function of a change-over valve is utilized. The advantage is the pipeline is not filled during filling or emptying of multiple vessels. The pipeline is only open while the vessel is filled. This avoids an...
