Globe Valve

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.

DESIGN FEATURES

Globe Valve Body Styles

  • Y-Globe Stop, Check and Stop Check Valves
    Y-pattern globe valves provide the maximum Cv possible in a globe valve. All Y-pattern valves are rodable. Available in 1/2″ to 4″; ASME pressure classes through 4500; SA105, F22, F91, F316, F347, Inconel™, Monel™ and other materials.
  • T-Pattern Stop, Check and Stop Check Valves
    T-pattern, vertical stem globe valves provide easily accessible stems and extentions for remote manual operation. Available in 1/2″ to 3″; ASME pressure classes through 4095; A105, F22, F91, F316, F347, Inconel™, Monel™ and other materials.
  • Angle Stop, Check and Stop Check Valves
    Angle pattern globe valves economically eliminate the need for separate valves and 90° joints. They also reduce the number of installation welds. Available in 1/2″ to 4″; ASME pressure classes through 4095; A105, F22, F91, F316, F347, Inconel™, Monel™ and other materials.

Valve packing system

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.

Rapid In-Line Repairability

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.

Pressure Seal Bonnet

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.

Single-piece Gland

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.

Axial-Loaded Packing System

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.

Pressure-Actuated Backseat

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.

What is a Globe Valve?

Globe valves are linear-motion valves that stop, start, and regulate the flow of liquids and gases through process systems. These valves are precisely designed to accommodate specific ranges of flow control and pressure drops, which enables them to avoid premature failure and ensures optimal performance and service.

 

The Clampseal globe valve can be supplied with any of three of body styles, Angle, Y-pattern and T-pattern.  The rest of the valve stays the same, but the body style choice results in different characteristics and performance.  The Y-pattern body is also available with integrally forged Grayloc® ends.

Angle Globe Valves

As the name implies, angle globe valves channel fluids at 90° angles  The angle valve is frequently specified when a valve is needed close to an elbow as combining the valve and the elbow will save weight and welds resulting in lower cost.

Y-Pattern Globe Valves

Y-pattern globe valves position their seat and stem at a 50° angle, which allows for a straighter flow path at the full opening. This attribute also provides the least flow resistance, which enables the entire system to work more efficiently.

T-Pattern Globe Valves

T-pattern globe valves position their seat and stem at a 90° angle, which places the handle or actuator directly above the valve at the expense of lower flow than the Y-Pattern.   This configuration can be an advantage in supporting an actuator.

Materials

We stock our forged bodies in A105, F22, F91 & 316 as standard materials.  We have provided our customers with valves in over 30 alloys such as F92, Inconel®, Incoloy®, Monel®, Hastelloy®, 347, Sandvik 2RE69, to meet their particular requirements.  We consider it one of our strengths that we can supply any alloy that the customer wants.

End Configurations

The customer specifies how they want to insert the valve into their pipeline.  We offer:

  • Buttweld ends, metric or English
  • Socket weld ends
  • FNPT threaded ends
  • Grayloc® flanged ends
  • ANSI Flanges
  • API Ring Joint Flanges
  • Whatever ends you want
