Rugged and reliable through-conduit valve

The Grove™ G7 fabricated gate valve has a smaller body cavity volume compared with traditional cast gate valves. It uses two floating seats to provide a complete seal with the gate. Each seat has a metal face and a peripheral seal. The fullbore design creates the same pressure drop as an equivalent length of pipe and allows passage of all types of scrapers (pigs).

The valves are designed for a wide range of applications, including

• mainline and manifold valves
• tank and station valves
• storage wells
• meter bypass valves
• hot tap valves
• CCUS and renewable fuels service.

Reliable performance and long life

The Grove G7 valve's through-conduit design provides the following advantages:

• smaller body cavity volume, leading to reduced product contamination
• protection of seat faces
• smooth, continuous conduit for flow
• block-and-bleed capability
• inline field repairs
• fire safe certification to API Spec 6FA and ISO 10497
• fugitive emissions certification per ISO 15848-1.

• Enhanced fabricated body construction is less prone to raw material defects and can accommodate volumetric and surface nondestructive examination (NDE).
• The stem seal is a single fugitive emissions– and fire-tested SLS™ spring-loaded lip seal, which reduces maintenance requirements and eliminates the need for plastic packing.
• Spring-loaded seats relieve internal body pressure.
• Stem back seat per API Spec 6D prevents stem ejection.
• Metal-to-metal seal between the stem and bonnet in the upward position isolates the stem seal from line pressure.
• Seat and stem injection of lubricant or emergency sealant reduce operating torques, help increase valve life, and provide emergency sealing capability.
• Installation orientation is flexible.
