PRODUCT PROFILE: BENCHMARK BM15 SERIES SERVO VALVE
January 6, 2010
The Benchmark BM15 series servo valve is a high performance, two stage valve utilizing a nozzle flapper pilot and a force-feedback design control. The BM15 has been extensively tested to assure that it is 100% compatible with MTS, Moog models 760, D761, A076; Atchley 215 and 218; Vickers models SM415 and SM420; Schenck Pegasus models 132, 142, and 162. Mating electrical connector is a MS3106F-14S-2S and mounting manifold conforms to ISO 1032-04-04-0-92.
Benchmark Products are direct equivalents to many currently available hydraulic products in the market today. Due to a in-depth reverse engineering process, Benchmark products are, in many instances, better than the original, decades old designs. The BM15 servo valve is thoroughly tested to guarantee performance levels that meet or exceed original manufacturers’ specifications.
