Mark 7 Series Sliding Gate Control Valves The MK7 Series is a line of pneumatically-operated diaphragm control valves that combine multiple spring actuators with the precision of Jordan Valve s advanced sliding gate seat for closer control and greater accuracy. Jordan s unique sliding gate control valve trim teams up with pressure, temperature, ph, level, or flow controllers for fast response, long term reliability, and high levels of accuracy on steam, gas, liquid and chemical services. Consisting of a modulating disc and stationary plate, the sliding gate seat components are slotted with multiple orifices that align to provide the precise flow needed to maintain the process requirements. The valve strokes in a fraction of the travel required by conventional control valves for rapid correction of any deviation from the process setpoint. This brochure includes the following Series: MK7: a line of pneumatically-operated diaphragm control valves that combine multiple spring actuators with the precision of Jordan Valve s advanced sliding gate for closer control and greater metering accuracy MK7PG: the MK7PG is a pump governor with its control port connected to the pump discharge line. The valve throttles to maintain a constant pump discharge by controlling the steam flow to the pump. MK71/72: The MK71/72 is for higher capacity requirements. MK77: The MK77 features an equal percentage flow characteristic. MK711: The MK711 is a linear control valve in sizes up to 6 with Cv s to 395 (339,7 Kv). MK74: The MK74 controls fugitive emissions while reducing the risks associated with toxic, corrosive, explosive and high temperature fluids. MK: The MK is a low profile, lightweight on-off control valve. MARK 7 FEATURES Totally enclosed multi-spring actuator minimizes deadband and is field reversible without the use of special tools or additional parts Compact design and simple construction allows fast, simple installation and easy maintenance Sliding gate seats provide Straight-through flow for reduced turbulence and quiet operation Short stroke for fast response and accurate control Easily interchangeable Cv s Tight shutoff due to overlap of seat closure area Stem packing is four times deeper than stem travel for greater protection against leakage Jordan Valve, a Division of Richards Industries 317 Wasson Road Cincinnati, Ohio 4529 Telephone 513-533-56 Fax 513-871- Toll-FreeTelphone: 8-543-7311 (U.

Mark 74 Series Bellows Seal Control Valve When dealing with clean air requirements, you need to feel confident that you will receive long-term, leak-free performance from your bellows stem seal valves. You will find this assurance with the Mark 74 from Jordan Valve. The Mark 74 provides exceptional bellows life with a valve stroke that is just a fraction of that of other rising stem valves. This means Jordan Valve can use a smaller formed bellows that has minimal movement during operation. With limited movement, the bellows is not subjected to excessive wear and fatigue conditions that can quickly lead to failure in other designs. In actual laboratory evaluations the valves tested exceeded two million throttling cycles in Class 3 service with no failures of the bellows. You can expect the Mark 74 to provide long-term, dependable service to meet Clean Air requirements. For compliance with the most stringent requirements of the Clean Air Act, the Mark 74 controls fugitive emissions while reducing the risks associated with toxic, corrosive, explosive and high temperature fluids. FEATURES Long bellows life in actual lab tests, the Mark 74 exceeded 2 million cycles with no bellows failures Short stroke with a valve stroke that s just a fraction of that of other rising stem valves, the Mark 74 uses a smaller bellows that has minimal movement during operation. With limited movement, the bellows is not subjected to excessive wear and fatigue, conditions that can quickly lead to failure in other valve designs Fully packed back-up seal for additional assurance, a secondary chamber of multiple packing rings provides extra leakage protections Detection/monitoring port a gauge can be mounted to verify bellows performance Totally enclosed multi-spring actuator minimizes deadband and is field reversible without the use of special tools or additional parts Specialty alloys available ideal for toxic or corrosive services SPECIFICATIONS s: 1/2 (DN), 3/4 (DN2), 1 (DN), 1-1/4, 1-1/2 (DN4), 2 End Connections Threaded (FNPT, BSPT, BSPP) ANSI Flanges (#, ) N Flanges (PN, PN) s Ductile Iron Bronze Carbon Steel (WCB) Stainless Steel (CF8M) Trim s: 33 Standard on Ductile Iron, Bronze, or Carbon Steel valves 316 Standard on Stainless Steel valves Seat s: on Standard /Jordanic on For Severe Service Chrome Plated Economical option for light duty service Bellows: 316SS Hastelloy C -14-
