1. A valve assembly comprising:
a housing comprising:
an inlet port, at a first end of the housing, configured to receive a fluid;
an outlet port, spaced from and substantially perpendicular to the inlet port, configured to discharge the fluid; and
an assembly portion, at a second end of the housing distal from the inlet port, the assembly portion comprising an opening and helical grooves around the opening; and
a poppet-carrying portion configured to be inserted through the opening of the assembly portion, the poppet-carrying portion comprising:
a poppet head, at a first end of the poppet-carrying portion, configured to fit within the housing;
a closure, at a second end of the poppet-carrying portion, comprising protruding arms;
at least one convolution extending between the poppet head and the closure, configured to allow the poppet head to compress and extend relative to the closure; and
a stopping portion, extending from the closure toward the poppet head and spaced apart from the poppet head by a maximum compression distance, the stopping portion configured to limit compression of the at least one convolution to the maximum compression distance;
wherein, at a first fluid pressure, the protruding arms engage with the helical grooves, and the poppet head is positioned in a pre-load position that prevents the fluid from discharging through the outlet port.
