LV General-purpose Stainless Steel Quick Release Coupling

 

 

Features
LV series quick release couplings are general-purpose medium/high pressure quick release couplings which can realize self sealing after split. LV series quick release couplings feature high cost performance, diverse types of connections and compact structure. The standard material is 304 stainless steel. They are applicable to water, air, oils and other media compatible with the coupling material.

 

Type of construction:dual-closed; male and female couplings are both self-sealed.

 

Operating PrincipleBoth male and female couplings may have a self-sealing valve. The male and female couplings push open the self-sealing valve of each other after coupled, and the passage is open; disconnect the male and female couplings by pulling the extension sleeve and the valves are automatically closed by the spring, thus preventing liquid spills.

 

Application of Sealing Materials

 

Code Name of Material Uses 
F FPM (standard) Good corrosion resistance; applicable to most media; intolerant of ammonia, alcohols and diethyl ether; temperature range: -25℃~+180℃
E EPDM(optional) Intended for ammonia, acetic acid, methanol and steam; mineral oil intolerant;  temperature range: -50℃~+120℃
