VAN CẦU HƠI CLASS 1500/2155, LOẠI 5F, FIG.NO.: 1.50-G5CJ-A105F, CONVAL-USA
CLAMPSEAL® Globe Valves are tailored to the exact requirements of our customers. No other severe service forged valve offers so many options. Conval provides three globe valve body styles, Y, Angle, and T-Pattern, in ASME pressure classes through 4500 and five standard materials. Other materials are available to meet customer needs. The easy interchangeability of parts means that an entire plant installation can be supported with a very low parts inventory.

The CLAMPSEAL® packing system incorporates corrosion-inhibited, high-density graphitic packing. Uniform loading from the axial one-piece gland and the highly polished stainless steel stem and stuffing box ensure a tight seal between packing material and sealing surfaces.
The CLAMPSEAL® globe valve is much easier to repair than anything else on the market. The CLAMPSEAL® globe valve line provides a modular solution to rising maintenance expense. Low first cost is not as important as low cost over the serviceable life of a valve. Maintaining a Conval valve is far easier and much less costly than replacing a competitor’s valve.
The simple and effective pressure seal bonnet provides ready access for servicing with no welds to cut or seal rings or gaskets to replace. The body-to-bonnet joint integrity is maintained through countless thermal cycles.
In extreme environments, the simpler the design and the fewer the parts, the better. The durable single-piece stainless steel gland contributes to the longevity of the valve.
The Axial design ensures tight concentricity, which eliminates side loading of the packing and minimizes wear forces on the trim components. This feature is critical for superior valve performance.
The CLAMPSEAL® pressure-actuated backseat provides maximum valve integrity by ensuring a positive internal stop for the valve stem and disc assembly. The pressure actuated backseat also extends packing life by securely isolating the packing from the pressure when the valve is fully open.
