I want to replace a 25 psi bypass conical helical compression spring by a 50 psi bypass spring.

The 50 psi spring has to fit in the same space slot as that of the 25psi spring.

The dimensions of the 25 psi bypass spring are 1.110" od - big end ; 0.760" - smaller end ; no restrictions on the ID.

Please send/ inform me what software is available online .

also please send me the detailed procedure to design the spring.

regards,
