Hawe Hydraulics Pvt. Ltd. Manufactures Pressure Limiting Safety Valves. Hawe Hydraulics Pvt. Ltd. Is an ISO 14001:2005 certified company. The Pressure Limiting Safety Valves are used for safeguarding the system against excessive pressure or for the limitation of working pressure. They are also used for generating a constant pressure difference between inlet and outlet of the flow. The flow in opposite direction [reflow] is unhindered via a by-pass check valve. The advantage of these Pressure Limiting Safety Valves is their easily to manufacture mounting hole. Type CMV is also available as a pressure limiting valve with unit approval [CE], e.G. Required for safety valves for accumulators [EC regulation 97/23]. The CE-logo is applied to these valves. Type CMVZ und CSVZ are not influenced by the pressure conditions downstream i.E. Sequencing control without Losses.
