BGV STAINLESS STEEL GATE VALVE WITH LOTO SAFETY FEATURE Giving you a clear edge PRODUCT DATASHEET Edwards BGV LOTO pneumatic gate valves include all the benefits of the standard BGV range, with LOTO safety feature and low power. BGV LOTO gate valves are bellows sealed stainless steel gate valves for use in applications which require high leak tightness and a minimum of hydrocarbons in the vacuum system. Although principally designed for the isolation of pumps in the semiconductor fab basement, BGV valves are also ideal for other applications where a 1 bar differential at opening is desirable. The unique Lock-Out-Tag-Out (LOTO) safety mechanism allows personnel to freely work on the vacuum system without fear of the valve inadvertently opening. The valve is physically held closed using a pin to lock the valve shut preventing it from being opened. If there is a requirement for the valve to be locked shut, a lockout hasp can be inserted through the LOTO pin and padlocked. They are designed for use in the pressure range of 1.2 bar absolute to 1 x 10 -9 mbar (1.2 x 105 to 1 x 10 -7 Pa). BGV valves will withstand 1.2 bar absolute in either direction allowing the vacuum line above the pump to be vented with the valve closed. The low power actuation requirement at just 1 W enables direct connection to Edwards latest generation dry pumps range without any additional external power supply, and facilitates ‘plug and play’ simple installation. Reed switches can be used by your control equipment to determine if the valve is open or closed, these also contain LEDs to provide a visual display of the valve position. Each valve is fitted with a 24 V AC/DC solenoid and pre-wired plug for direct connection to your Edwards latest generation vacuum pump. This 15-way “D” plug offers a single point of connection for both power to the solenoid and the signal from the reed switch position indicators. LOTO valve can be locked securely closed Providing a safe working environment during maintenance Pneumatic solenoid and pre-wired option Pre-configured simple ‘plug and play’ installation Low power actuation at just 1 W Direct connection to Edwards latest generation dry pump Stainless steel construction and robust design Long service life and reliability in harsh environments Able to withstand 1.2 bar absolute in either direction Allowing the pump to continue running during maintenance Simple grease-free sealing mechanism Minimises damage due to particulates in dusty processes

Key Features The simple but innovative wedge sealing mechanism, incorporating PEEK gliders, make the valve especially suited to applications with high levels of process by product in the gas stream: • No oil, grease or complex moving parts within the valve removing the risk of damage to the mechanism due to contamination from process debris. • PEEK gliders provide no metal-to-metal contact and act to control the compression of the O ring. • As the gate closes the O ring brushes across the sealing surface briefly before it seals, helping to clean debris from the sealing surface thus giving a...
