3 . The check valve of claim 2 , wherein the compression device further comprises:
a valve stem connected to the first and second sealing mechanisms wherein one end of said valve stem extends into the stem guide of the valve housing; and
a spring disposed around the valve stem, the spring exerting a force on the first and second sealing mechanisms.
4 . The check valve of claim 3 , wherein the valve stem is mechanically connected to the valve head of the first sealing mechanism.
5 . The check valve of claim 3 , wherein the valve stem is mechanically connected to the seal retainer of the second sealing mechanism.
6 . The check valve of claim 5 , wherein the seal is mechanically connected to the seal retainer of the second sealing mechanism.
7 . The check valve of claim 1 , wherein the valve housing further comprises a valve seat having the input opening and a spring retainer having the output opening, wherein the valve seat and the spring retainer are coupled to form the valve housing.
8 . The check valve of claim 7 , wherein the valve seat and the spring retainer are mechanically connected using threading on the valve seat and the spring retainer.
9 . The check valve of claim 7 , wherein an interior surface of the spring retainer is coated with rubber, elastic polymer, phenolic resin, metal, any other suitable material or a combination thereof.
10 . The check valve of claim 1 , wherein an interior surface of the valve seat comprises rubber, elastic polymer, phenolic resin, metal, any other suitable material or a combination thereof.
11 . The check valve of claim 1 , wherein the valve head comprises rubber, elastic polymer, phenolic resin, metal, any other suitable material or a combination thereof.
12 . The check valve of claim 1 , wherein overmold layer further comprises a protruding lip configured to interface with the valve housing.
13 . A check valve comprising:
a valve housing having an input opening and an output opening;
a first sealing mechanism disposed in the valve housing, the first sealing mechanism having a valve head coupled with an overmold layer, the overmold layer further comprising a protruding lip configured to interface with the valve housing; and
a compression device coupled to the first sealing mechanism, wherein the compression device is configured to exert a force on the first sealing mechanism.
14 . The check valve of claim 13 , wherein the valve housing further comprises a valve seat having the input opening and a spring retainer having the output opening, wherein the valve seat and the spring retainer are coupled to form the valve housing.
15 . The check valve of claim 14 , wherein the valve seat and the spring retainer are mechanically connected using threading on the valve seat and the spring retainer.
16 . The check valve of claim 14 , wherein an interior surface of the spring retainer is coated with rubber, elastic polymer, phenolic resin, metal, any other suitable material or a combination thereof.
17 . The check valve of claim 13 , wherein an interior surface of the valve seat comprises rubber, elastic polymer, phenolic resin, metal, any other suitable material or a combination thereof.
18 . The check valve of claim 13 , wherein the valve head comprises rubber, elastic polymer, phenolic resin, metal, any other suitable material or a combination thereof.
19 . The check valve of claim 13 , wherein the valve head has an oblong configuration.
20 . A check valve comprising:
a valve seat having an input opening and a spring retainer having an output opening, wherein the valve seat and the spring retainer are coupled to form a valve housing;
a first sealing mechanism disposed in the valve housing, the first sealing mechanism having a valve head coupled with an overmold layer wherein the overmold layer further comprises a protruding lip configured to interface with the valve housing;
