Stop valves type ZOPb and ZOKb Stop valves are designed mainly for land and marine refrigerating equipment. There may be used wherever there is a need to shut-off the flow of refrigerant in vapour or liquid state.

Three-way valves type ZTb Three - way valves are designed mainly for land and marine refrigerating equipment, equipment for propane -butane gas as well as for other equipment for inactive mediums. The purpose of the three - way valves is to prevent an interruption of the flow of the refrigerant from an apparatus to safety valves.

Control valves type ZRPb Control valves are designed mainly for land and marine refrigerating equipment. They are used to throttle the refrigerant from the condensing pressure to evaporating pressure and for stepless control of quantity of flowing liquid

Non - return valves type ZZPb and ZZKb Non - return valves are designed mainly for land and marine refrigerating equipment, equipment for propane-butane and other non-aggressive agents to carbon steel. They are used wherever it is necessary to prevent from the return flow of refrigerant in the piping.

Preliminary filters type FWPb, FWKb, FWPk and FWKk Preliminary filters are designed mainly for land and marine refrigerating equipment, equipment for propane-butane gas as well as for general-purpose equipment for inert chemical agents. They serve as cleaners of refrigerant in installation from major waste products and impurities, which protects machines and devices against disruption in functioning as well as extends their durability.

Safety valves type ZBKk Safety valves are designed mainly for land and marine refrigerating equipment, equipment for propane-butane and other non-aggressive agents. Safety valves are applied to protect equipment against excessive rise of pressure, as mechanical solution.
