Combined Check Valve

Combined Check Valves or Hydraulic actuators weight loaded HAWL valves are used at all critical areas where the pipelines must be reliable, immediate and controlled quickly for valve closing, e.g.

in case of external power losing, cutting off electricity cables during The earthquake, disasters In a system, ruptured pipelines, etc.) While for the valve closing is used a potential energy of lifted weight.

Nozzle Check Valves

The nozzle check valve is one of the faster closing check valves that reduce slam and water hammer due to its short linear stroke.

The nozzle check valve design also reduces head loss during operation. Hence is one of the most economical valves.
