MDC Pneumatic High Vacuum Rectangular Gate Valve LVHC-18SB
This is an MDC Vacuum Products Corp. pneumatic high vacuum rectangular gate valve LVHC-18SB. MDC LVHC series rectangular gate valves meet or exceed all applicable MESC* standards. LVHC valves incorporate a patented one piece gate and carriage design that virtually eliminates vibration and particle generation. O-ring scuffing and wear are non-existent because of a floating driver bar design. The one piece gate and carriage can be removed through the valve's bonnet flange for gate seal replacement, cleaning, etc., without disassembling the valve body from the system. The LVHC-18-SB has a flange-to-flange thickness of 2.75" (70 mm), with rectangular port dimensions of 1.25 x 8.75" (32 x 222 mm). These valves are designed for use in high vacuum load-lock systems in semiconductor processing, where low vibration and low particle generation are imperative. The valves' low outgassing characteristics can be attributed to a fusion welded 300 series stainless steel body, welded AM-350 stainless steel nesting bellows as well as small cross section O-rings and the elimination of blind internal cavities. Custom design valves are available on request. Pneumatic actuators are fitted with mechanical position indicators which indicate fully open and fully closed positions. This MPI system consists of two single pole, double throw micro switches fitted with integral hinged lever and roller actuators. Each micro switch is wired in a normally open position via a 7-pin circular threaded connector. Precise positioning of micro switches is made possible by a patented vernier adjustment mechanism only available on MDC gate valves. Pneumatic actuators are equipped with dual impulse Herion 24 V DC air control solenoid valves. All solenoid valves are fitted with DIN type connectors that conform to international standards. DIN connectors provide simplicity, convenience and fast, easy electrical installation. Solenoid valves are designed for use with compressed air from 0 to 125psig. *SEMI, short for 'Semiconductor Equipment & Materials International' developed the 'Modular Equipment Standards Committee', better known as MESC, to establish global interchangeability and modularity between products from the numerous sources in the semiconductor manufacturing equipment and components industry.
