General Twin Seal
Double Block & Bleed
Stock available today in 2″ – 36″, ANSI 150# – #900
Introduced in 1941, GENERAL VALVE Twin Seal plug valves, also known as a Double Block and Bleed Valve, were the first to meet the rigid requirements of double block-and-bleed service. In the years since, subtle yet significant design refinements have further improved valve performance. Superior design innovations, pride in manufacturing workmanship, and selection of the best materials support our commitment to excellence and customer satisfaction.
Zero-Leakage Double Block-and-Bleed Plug Valve with Retracting Seals
In meter block service, the differential pressure across each closed valve is very low. No assistance is required from the line pressure to energize or compress floating seals to make them hold tight. The seals typically rely on springs to press them against the ball unless the body cavity in a ball valve is vented. The ball valve may be leaking until the user opens the bleed. Then, the reduction of the body pressure introduces a hydraulic force on the seat that may stop the leak. The user can form a false impression that the ball valve is holding tight, when in reality, it leaks. In contrast, the mechanical wedge action of the valve plug compresses both the upstream and the downstream seals firmly against the valve body, needing no help from the line pressure.

ORBIT VALVE
Rising Stem Ball

T3 Standard , T5 Ammonia , T7 NACE with H & H8 seats options
ORBIT rising stem ball valve’s unique tilt-and-turn design reduces seal rubbing and delivers reliable performance. It is the proven technology for arduous process conditions, including high-temperature, critical isolation to molecular sieve switching services. This legacy of innovation began in 1912, when Alfred Heggem founded The Oilwell Improvements Company of Tulsa. Heggem’s groundbreaking ball valve seating principle, patented in 1935, was considered by many at the time to be the first major advancement for valves in half a century. This patent is the forerunner to all ball valves today.
Nearly 80 years later, the same engineering technology still is used to safeguard against seat rubbing—a leading factor for why ORBIT valves are world-renowned for high integrity and long service life.
ORBIT Low-E certified low emissions valve
Not all valves are created equal. Only ORBIT Low-E valves incorporate new sealing elements that have earned certification to ISO 15848 Tightness Class AH and API Standard 622 for both high- and low-temperature applications. By integrating advanced graphite-based technology with the proven ORBIT valve tilt-and-turn operation, ORBIT Low-E valves set a new benchmark for fugitive emissions (FE) performance at temperature extremes while increasing valve life even under dynamic cycling conditions.

The Cameron WKM Saf-T-Seal slab gate valve is a simple, yet rugged and reliable, through-conduit valve. It utilizes two floating seats to provide a complete seal with the gate. Each seat contains a metal seat face plus a peripheral seal. The full bore design has the same pressure drop as an equivalent length of pipe and allows passage of all types of scrapers (pigs).
The WKM Saf-T-Seal gate valve’s through-conduit design provides these specific advantages resulting in reliable performance and long life:

The GENERAL VALVE Four-Way diverter valve
Stock available today in 3″ – 16″, ANSI 150# – 600#
The GENERAL VALVE Four-Way diverter valve does not rely on line pressure or external hydraulic pressure for positive sealing.
The seating elements, or slips, move perpendicularly against the face of the ports. The seals themselves are highly resilient elastomers that are either bonded or mechanically retained in the slips. Retraction of the slips away from the body prior to cycling prevents friction and abrasion, which can damage seals. There is never any sliding or rubbing of the seals against the valve body or ports.
Metal-to-metal secondary seating prevents overcompression of the resilient primary seal. Mechanical retraction and compression ensures no-leak stream separation and longer life.
