50Spring energized seal for hot melt adhesive injection machine
The sealing ring has a crucial influence on the phenomena of rubber valve leakage, consistent size of rubber discharge, flow rate, bubbles in the fluid, etc.
The seal jacket of adhesive dispenser/dispensing seal is made of ultra-high molecular UHMWPE or PEEK, with installed stainless steel anti-corrosion spring with low temperature resistance treatment. It can work in normal pressure and vacuum environment for a long time, and can seal under different working conditions of hot and cold adhesive.
The spring energized seal of dispensing machine is mainly a hydraulic pneumatic seal, which is applied to various dispensing valves, piezoelectric valves, jet valves, glue valves, pneumatic valves, screw valves, glue sprayers and other dispenser pins, nozzles, dispensing needles, solder nozzles, paint nozzles, SMT suction nozzles, dispensing nozzles, integrated nozzles, split nozzles, micro spray valve nozzles, non-contact dispensing valve nozzles, etc.

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.
In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
The oil scraper ring is a part located at the rear of the pump packing seal.
The water pump seal D1 is composed of one or couple of fabric reinforced Chevron V rings (DM), back up ring (DD) and header ring (DS) for plunger sealing.
JST's ESU series stem packings, also known as u packing, are designed to be placed between the stem and bonnet of Type FC gate valves. This stem packing gives you a reliable seal for superior performance.
Spring energized PTFE seals consist of variety of jacket profiles and spring types. It can achieve the sealing effect compensation under different pressure conditions by spring energizer.
The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material.
Oil-free Air compressor PTFE piston cup seals extensively used for steam, oil, water, and other chemical applications.
