Our Products

The Y-pattern globe valve (also called straight-through or oblique-stem globe valve) has its stem set at an angle to the body bore axis, so the medium passes through almost in a straight line and the flow resistance is only about one third that of a straight-through globe valve. It combines the sealing performance of a globe valve with flow resistance close to that of a gate valve. It is suitable for media that are highly viscous, high-velocity, prone to crystallisation or contain a small amount of solids, such as steam, heat-transfer oil and slurry lines, where it serves for shutoff and regulation. It is a common valve type for high-temperature, high-pressure steam blowdown and condensate systems.

Features

· Straight-through oblique-stem design, flow resistance about 1/3 of the straight-through type · Combines globe valve sealing with pressure loss close to a gate valve · Suitable for high-viscosity, crystallising and solids-laden media · Seating surface can be hardfaced with a hard alloy · Flanged or butt weld connections · Handwheel / gearbox / electric operation

Bellows-Sealed Globe Valve

The bellows-sealed globe valve places a metal bellows between the stem and the body as the primary seal, completely isolating the medium in the stem movement area from the outside. Together with graphite packing it forms a dual seal that eliminates external leakage at the packing, making it a critical valve for conveying toxic, flammable, volatile and valuable media. The bellows is made of corrosion-resistant materials such as 316L/Inconel and passes helium mass-spectrometer leak testing. Combined with an anti-blowout stem and live-loaded packing, low fugitive emission designs can be supplied to the classification requirements of ISO 15848-1. It is widely used in steam, heat-transfer oil, ammonia, chlorine and hazardous chemical lines.

Angle Globe Valve

The angle globe valve has its inlet and outlet arranged at a 90° right angle, so the medium changes direction once inside the valve. The design is compact and can replace a pipe elbow directly, reducing fittings and welds. The seating surface is usually hardfaced with a hard alloy, which suits media with high differential pressure, solids content or a tendency to coke, such as black water in coal chemical plants, coking units and high-pressure blowdown lines. Vertical installation keeps material from accumulating inside the valve and allows complete draining.

Flanged Globe Valve

The flanged globe valve opens, closes and regulates flow by lifting a plug-type disc along the seat centreline; the seating surfaces are a flat or conical pair, giving reliable sealing and easy maintenance. Compared with a gate valve, the flow passage of a globe valve is S-shaped, so flow resistance is higher, but the valve offers a degree of flow regulation. In the standard straight-through design, the body is usually closed by a bolted flanged bonnet, and the seating surface can be hardfaced with 13Cr (Trim 1), Stellite 6 (Trim 5) or Monel (Trim 8) to suit different media. It is used in small-bore steam, water and oil lines where tight shutoff and throttling are required.
