Introduction Not all valves work the same, and when flow control needs to be exact, it helps to know what’s out there. An expanding gate valve is one type that stands out. It opens and closes in a way that fully seals off product flow from both directions, giving a tight shut every time. For …
What Double Block and Bleed Valves Do in Lafayette Introduction A double block and bleed valve plays a key role in keeping pipeline systems safe and running steady. It’s a valve setup that can stop flow from both sides of a section and bleed off any pressure left in between. This setup helps workers stay …
Introduction Choosing the right four way diverter valve in Texas is never just about picking something from a spec sheet. It’s about finding a valve that can last through long hours, sudden pressure changes, and heavy cycles. These valves work everywhere in the state, from oil and gas pipelines to busy processing plants and distribution …
Introduction When equipment runs all day, every day, small parts can make a big difference. In places like Lafayette, where oil and gas work keeps things moving, you need valves you can rely on. Even one failing seal or damaged gate can slow things down. That’s why finding the right valve parts supplier in Lafayette …
Introduction Gate valves play a quiet but steady role in oil and gas operations across Texas. They’re the kind of parts that don’t always get attention until something stops flowing when it should stay moving. Whether it’s a pipeline out in West Texas or a terminal near the coast, these valves must hold up against …
Introduction Full bore ball valves are used across all sorts of pipeline systems in Texas, especially in high-volume oil and gas operations. These valves are built for strength and steady flow, which makes them a reliable choice in heavy-use setups. But like any piece of equipment, they don’t last forever. Wear and tear can sneak …
Introduction When valves start acting up, work at busy Lafayette sites can grind to a halt. Whether it’s an old seal that won’t hold or a pressure change that throws the system off, one small part often has a big impact. That’s why it helps to have a trusted valve distributor in Lafayette who knows …
Introduction Pipelines in Texas do not get much of a break. Between the heat, abrasive dust, and pressure swings, these systems are working hard all year. As the weather starts to shift in September, the strain on valves and fittings can spike in ways that catch crews off guard. That is where a good pipeline …
Introduction Pipeline leaks can start small, but the problems they cause never stay small for long. In Lafayette, keeping everything moving safely and smoothly depends a lot on the gear inside the pipes—especially the pipeline valves. When something inside wears down or doesn’t fit the job, trouble has a way of showing up fast. This …
Introduction When it comes to flow control, the type of valve you choose makes a big difference. In high-pressure lines and tough field conditions, not every valve holds up the same way. That’s where a rising stem ball valve can stand out. This type of valve offers better handling in pipelines where shutting off flow …

Valve
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.

Through-conduit slab gate valve with floating dual seats
The Cameron WKM Saf-T-Seal slab gate valve is a simple, yet rugged and dependable through-conduit design. Two floating seats, each with a metal seat face and peripheral seal, provide a complete, bi-directional seal against the gate. The full-bore port produces the same pressure drop as an equivalent length of pipe and accommodates all standard pipeline scrapers (pigs), ensuring efficient flow and maintenance operations.
The through-conduit construction shields the seat faces from the flow stream, maintains a smooth uninterrupted conduit, and enables true block-and-bleed functionality—benefits that translate into reliable sealing and extended service life across a wide range of applications.
Stock available today in 2" – 36", ANSI 150# – 900 mCarrying T101 & T24 models with Low Alloy & T24 Stainless Steel Through-Conduit Parallel Expanding Gate Valve
The WKM Pow-R-Seal expanding gate valve delivers reliable, bi-directional shut-off in demanding pipeline and station service. Its parallel expanding gate/segment assembly achieves a mechanical seal that is independent of line pressure, while the full-bore flow path minimises pressure drop. Nickel-plated sealing surfaces and robust construction provide long service life in abrasive and high-cycle applications.
The stem seal is completely contained within the bonnet and supported by bearings that centralise the stem; a nickel-plated stem is standard. The self-adjusting seal does not rely on plastic packing, and its PTFE compound resists virtually all loadings. A pedestal supports the seal and functions as a stem scraper. Valves 6" to 24" (150 mm to 600 mm) in Class 300 to 900 are fire-tested to API 6FA 3rd Edition.
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.

Introduced in 1941, GENERAL VALVE Twin Seal plug valves, also known as Double Block and Bleed Valves, 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.
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.
