Dallas, Texas (PRWEB) July 14, 2014
Flowserve Corporation (NYSE: FLS), a leading provider of flow control products and services for the global infrastructure markets, today announced the launch of the Limitorque Hydraulic Scotch yoke (LHS) actuator. The LHS is ideal where hydraulic motive power is preferred and for services requiring a robust design, long service life, high-torque and high-speed operation. It is suitable for on/off, modulating and control applications of quarter-turn valves, specifically in the offshore environment as well as in general, protective and safety services such as emergency shutdown (ESD) or high-integrity pressure protection systems (HIPPS), up to and including SIL 3 Level in accordance with IEC 61508. The launch of the LHS marks another milestone, as Flowserve continues to expand its fluid- and electric-powered actuator portfolio produced under the Limitorque brand.
Designed to meet or exceed the most current and stringent safety and reliability standards for oil and gas services, the modular, hydraulically driven LHS is a piston-type, Scotch yoke actuator. It incorporates the same design philosophy and meets many of the same performance criteria as its pneumatic counterpart, the LPS, which was launched by Flowserve in January. Most notably, the LHS offers the same maintenance interval as the LPS — up to six years or as prescribed in EN 15714 for high-cycle applications — and an industry-leading, 25-year operational life.
“The release of the LHS actuator is another important step in the Limitorque fluid-powered portfolio expansion strategy,” stated Jeff Drees, president, Flowserve Flow Control Division. “Providing customers a heavy-duty option for applications where hydraulic motive power is preferred or required was an essential part of our product road map. We are very pleased by our team’s continued success developing products that meet today’s market requirements,” he added.
The ruggedly built LHS delivers up to 250 kNm (184,000 ft-lb) and a maximum allowable working pressure (MAWP) of 207 bar (3,000 psi), with minimal wear and maximum efficiency. An optional version with a maximum allowable working pressure (MAWP) of 345 bar (5,000 psi) is available upon request. The LHS is available in single-acting spring return or double-acting configurations for operation in a wide range of standard, low- and high-temperature environments — from -29 C (-20 F) for spring return units and -60 C (-76 F) for double-acting units up to 160 C (320 F). It has been designed and manufactured in accordance with: IP66/IP66M and IP67/IP67M per EN60529; NEMA 4 and NEMA 4X per NEMA 250; and EN 15714-4.
Information is available from Flowserve Limitorque regarding product compliance for ATEX, PED, ASME, SIL and GOST.
The launch includes custom controls packages upon request for most applications, including: hydraulic control panels; hydraulic power units; hydraulic accumulator racks; and self-contained units. Combined with the advanced features of the LHS actuator, end users benefit from high-torque, ultra-fast actuator response in emergency shutdown, isolation and modulating flow control applications.
