Spring controlling valve

A valve assembly comprising:

• a valve seat having a strike face;
• and
• a valve member configured such that a sealing element of the valve member moves into contact with the strike face and out of contact with the strike face so that movement of the valve member is driven, at least in part, by biasing the valve member toward the valve seat via a spring, the valve member comprising:
• (a) a bottom portion,
• (b) legs connected to the bottom portion,
• (c) a top portion connected to the bottom portion, the top portion at least partially defining a top surface, and the sealing element positioned, at least partially, between the top portion and the bottom portion,
• (d) a spring retaining recess positioned in the top portion, the spring retaining recess having a recess wall and a recess base, the recess wall having a wall edge and at least partially defining a recess diameter, the recess diameter being larger than a diameter of a spring when positioned within the spring retaining recess so that the spring is positioned within the recess diameter, the wall edge overhanging the recess base, and
• (e) a boss defining at least a portion of the spring retaining recess.

A spring-loaded valve assembly comprising:

• a valve seat;
• and
• a valve member comprising:
• a valve body including a strike face positioned along an outer profile, a sealing element defined by at least a portion of the strike face, and a spring retaining recess extending into the valve body, the spring retaining recess having an outer wall and an inner wall, the outer wall having an outer wall edge and the inner wall having inner wall edge, the inner wall at least partially defined by a boss extending from a lower surface of the spring retaining recess upward from a recess base of the spring retaining recess, along a valve body axis, toward a top surface of the valve body, the outer wall edge overhanging the recess base, and
• a spring having at least a portion thereof positioned within the spring retaining recess.

A spring-loaded valve assembly comprising:

• an outer housing;
• a valve body including a strike face positioned along an outer profile;
• a sealing element forming at least a portion of the strike face;
• a recess extending into the valve body and having a dovetailed cross section;
• and
• a portion of a spring positioned in the recess.
