HIGH VISCOSITY FLUID AND PASTE VALVES
LOCTITE ® POPPET VALVES Item Numbers: 986300 and 983914
LOCTITE ® STAINLESS STEEL POPPET VALVE Item Number: 982621
The Loctite® Poppet Valves are designed to dispense Loctite® brand high viscosity
anaerobic form-in-place gasketing products, structural acrylics, and silicones. The valves are
typically used in conjunction with a positive displacement pump or a pressure-time system.
They feature a suck-back capability and can operate at fluid pressures up to 625 psi. Item
986300 uses dispense nozzles with a bayonet style mounting that improves nozzle end
location and can withstand the high fluid pressures required of high viscosity fluid
dispensing. Items 983914 and 982621 are equipped with a 1 ⁄8" NPT outlet for Luer-Lok® and
standard needle dispensing. All valves have stroke adjustment capability and are treated
with a proprietary Loctite® coating to prevent premature adhesive curing.
Features:
• Poppet design gives valve “suck-back” feature
• Bayonet type mounting of nozzles provides end location repeatability
• Handles product pressures up to 625 psi
• Positive mounting surface
• High strength plastic material versions are specially treated
to be inert to Loctite® brand products
• Stainless steel version is also specially treated and
is recommended for abrasive and silicone products
