Offers extreme durability for the most demanding process applications. The robust dual containment design leads to increased safety. Sealed bellows are isolated from process meaning no maintenance. There is also easy in-situ cleaning and o-ring replacement. Improved pump performance is achieved by pump overload protection\/isolation and there are lower particles due to the integrated soft pump feature.<\/p>\n\n\t\t<\/div> \n\t<\/div> MORE INFORMATION<\/a>[\/vc_column][vc_column bg_type=”” dima_canvas_style=”” min_height=”” translate_x=”0″ dima_z_index=”0″ border_style=”solid” delay=”” delay_duration=”” delay_offset=”” width=”1\/3″ id=”” class=”” style=”” css=”.vc_custom_1524254840185{border-top-width: 1px !important;border-right-width: 1px !important;border-bottom-width: 1px !important;border-left-width: 1px !important;padding-top: 4% !important;padding-right: 4% !important;padding-bottom: 4% !important;padding-left: 4% !important;}” border_color=”#eeeeee”]

Has precision machined high strength aluminium body from solid 6061-T6 billet. This eliminates pinholes and virtual leaks that can appear from cast\/welded aluminium valves. Dual quad ring long life shaft seals give improved system up-time to 400,000 cycles and improved leak integrity. High performance PEEK components reduce friction and lower particle levels. With this valve there is lower cost and hydrogen outgassing than an equivalent sized stainless steel valve.<\/p>\n\n\t\t<\/div> \n\t<\/div> MORE INFORMATION<\/a>[\/vc_column][\/vc_row][vc_row no_margin=”true” no_padding=”true” equal_height=”true” bg_type=”bg_image” dima_canvas_style=”” translate_x=”0″ dima_z_index=”0″ animate_item=”” delay_duration=”” delay_offset=”” id=”” class=”” border_color=”” di_bg_image=”6808″][vc_column bg_type=”” dima_canvas_style=”” min_height=”” translate_x=”0″ dima_z_index=”0″ delay=”” delay_duration=”” delay_offset=”” width=”1\/1″]

Offers one of the smallest interior surface areas in the vacuum valve industry. In the open position, the seal plate o-ring is completely out of sight preventing any particulate or media flow to accumulate on the sealing surface. In the closed position, the one piece solid block design prevents any material build-up on the back side of the valve mechanism, dramatically reducing service and maintenance requirements.<\/p>\n\n\t\t<\/div> \n\t<\/div> MORE INFORMATION<\/a>[\/vc_column][vc_column bg_type=”” dima_canvas_style=”” min_height=”” translate_x=”0″ dima_z_index=”0″ border_style=”solid” delay=”” delay_duration=”” delay_offset=”” width=”1\/2″ id=”” class=”” style=”” css=”.vc_custom_1524254314623{border-top-width: 1px !important;border-bottom-width: 1px !important;padding-top: 4% !important;padding-right: 4% !important;padding-bottom: 4% !important;padding-left: 4% !important;}” border_color=”#eeeeee”]

HVA’s 4000 series Viton\u00ae sealed right angle valves are suitable for use in high vacuum systems and in less demanding positions in UHV systems. The seal is made with a Viton\u00ae O ring which is best for valves that must be opened and closed frequently. We can offer valves with the following features:
\n– Stainless Steel and Aluminium bodies
\n– Manual and Pneumatic versions
\n– CF and KF flanges
\n– CF flanged Angle Valves in stainless steel with Viton\u00ae seals
\n– KF and ISO Angle Valves in stainless steel and aluminium with Viton\u00ae seals<\/p>\n\n\t\t<\/div> \n\t<\/div> MORE INFORMATION<\/a>[\/vc_column][\/vc_row][vc_row bg_type=”” dima_canvas_style=”” translate_x=”0″ dima_z_index=”0″ animate_item=”” delay_duration=”” delay_offset=”” id=”” class=”” border_color=””][vc_column bg_type=”” dima_canvas_style=”” min_height=”” translate_x=”0″ dima_z_index=”0″ delay=”” delay_duration=”” delay_offset=”” width=”1\/1″]
