Established in 1993, Guanfa Valve Manufacture Co., Ltd. is specialized China servo valve manufacturer and distributor of valves, hoses, tubes and pipes. Our oem servo valves are suitable for acid, alkali, water, steam, seawater, coal gas and natural gas. They are widely used in petroleum, chemical, paper making, fertilizer, brewing and metallurgy. The use of specialized software of Pro/E and CAD has shorted the P&D and trial manufacture cycle, and greatly improved the service life and dependability of products. Our high-quality products have been exported to the North Amercia, UK, USA, Germany, Italy, India, France, Australia, Japan.

The electro-hydraulic servo valve from German and raster ruler made in German HEIDENHAIN Co. are synchronously adopted in both main oil cylinders, which forms a closed loop control, provides exact feedback and operation of slider, so bring high precision in bending and repeated orientation of slider.
The adoption of hydraulic protruding automatic compensation system provides a solution to the influence on workpiece by the deformation of slider in bending. The compensation capacity is adjusted automatically by NC system conveniently and precisely.
The device of rear apron, which is complete in function, can selectively control serveral rear rods whose components such as guide, lead screw, and bearing are all imported, which is reliable in precision.The parts assemblage of bed piece is convenient for transportation and processing and can guarantee the precision of whole set.
The analysis of key components such as bed piece and slider through finite element analytic software of ANSYS gaurantees the reliability of machine tool.

Servo-Valve Externally Biased, Cardioid Condenser w/ 1.1" Capsule and Enhanced Harmonics. Hi-pass filter (80Hz roll-off). 20dB non-capacitive pad. High SPL capability. Includes external power supply, shock mount and swivel mount.
The M9 is a cardioid single tube externally biased condenser microphone that features servo-valve technology. The M9 is a natural bridge between the valve technology developed for the VX2 microphone and the servo opamp technology developed for the M-Series microphones. The head amp in the M9 microphone is a 12AX7 tube in a circuit that is optimized for super wide dynamic range and low noise. The output stage is a high speed dual opamp in a balanced differential configuration that allows long cables to be used without affecting microphone performance. 30 ft. professional quality 7 conductor cable with gold plated XLR male and female connectors. MV200 Analog Power Supply. Line Cord. Rugged carrying case.
Suspension Shock Mount.
