RVM Systems 11 RVM system for Chemical and Petrochemical applications The natural choice for Safety Instrumented Systems in downstream applications, the Herion 2401x or 980xx series solenoid valves have been successfully used in the Chemical and Petrochemical industries for over 40 years, gaining a reputation for reliability and safety. Available in aluminium or stainless steel, key features include an interchangeable coil system and optional valve position feedback sensors. Benefits Compact or modular manifold designs Interchangeable solenoid coils Reduced potential leak paths Integrated outlet filter to protect against particle ingress Modular construction enabling standard and customised solutions Fast, simple removal of individual components Bypass function for online valve replacement Up to 12 years SIL maintenance service intervals 12 year 24011 series, 6+2 year 24010 series, 6+2 year 980xx series Large reduction in installation time Cable terminations inside coil housing negating the need for additional ex certified termination enclosures Standard and high flow options Integrated exhaust guards preventing moisture ingress Specification Aluminium, or stainless steel construction IEC 61508 SIL based on field reliability data DIN EN 161/3394 DVGW type examination; Automatic shut off / control valves 1oo2, 2oo2 and 2oo3 options providing "safety", "availability" or "safety & availability" functionality Inductive proximity sensing of valve poppet position 1/4 and 1/2 porting options Temp. range: 24011: -40°C to +110°C (-40°F to +230°F) (depending on sealing material) Temp. range: 24010: -25°C to +80°C (-13°F to +176°F) Reliable direct acting poppet valve operating from 0 to 10 bar (0 to 145 PSI) Temp. range: 980xx: -40°C to +60°C (-40°F to +140°F) SIL Version: -25°C to +60°C (-13°F to 140°F) 10 times factor of safety, on solenoid de-energising return force Approvals IECEx, INMETRO, FM, CSA, NEPSI, TR-CU, CCOE & SIL V87 - Semi modular RVM without bypass V82-Compact RVM V81-Modular RVM with bypass
