Abstract:
An embodiment includes a gate valve comprising: a valve body including a cavity coupled to a channel having proximal and distal portions; a gate to seal and unseal the channel; proximal and distal seats adjacent the gate; wherein (a) the proximal seat traverses towards the gate and stops at a first position when the gate is closing and the proximal channel portion is more highly pressurized than the cavity, and (b) the distal seat slides away from the gate and stops at a second position when the gate is closing and the cavity is more heavily pressurized than the distal channel portion. Other embodiments are described herein.

Claim (Index 1):
A gate valve comprising:\n a valve body including a cavity in fluid communication with a channel, having proximal and distal channel portions, which extends between proximal and distal valve body portions; a gate configured to seal the channel in a closed gate position and unseal the channel in an open gate position; a proximal seat between the proximal valve body portion and the gate and a distal seat between the distal valve body portion and the gate, the proximal seat including an annular groove on an outer surface of the proximal seat; and a seal, which directly contacts the valve body and the proximal seat, including (a)(i) a first ring contacting a first spring and a second ring contacting a second spring, (a)(ii) first and second spacers located between the first and second springs, and (a)(iii) an annular ring included in the annular groove and between the first and second spacers; wherein (a) the proximal seat slides towards the gate and then stops at a first position when the gate transitions to the closed gate position and the proximal channel portion includes fluid more highly pressurized than fluid included in the cavity, (b) the distal seat slides away from the gate and then stops at a second position when the gate transitions to the closed gate position and the cavity includes fluid more heavily pressurized than fluid in the distal channel portion, and (c) the first and second springs are not included in the annular groove.
