The Most Advanced Forged Steel Valve Available
Axial Design
The axial design of CLAMPSEAL® valves ensures tight concentricity. This feature is critical
for superior valve performance. Concentricity eliminates side loading of the packing and
minimizes wear forces on the trim components.
High Performance Packing System

The CLAMPSEAL® packing system incorporates corrosion-inhibited, high density graphitic
packing. An optional LIVE LOADED GLAND system maintains packing loads for long periods
without routine maintenance adjustments. 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.
Integral Gland Wrench – I.G.W.

The Integral Gland Wrench makes packing adjustments simple, no tools required.
Clampseal® Bonnet/Chamber
A secure, leak proof bonnet allows rapid access to valve trim for inspection and
maintenance. The pressure boundary is sealed at the smallest diameter possible to ensure
maximum strength, low stress and minimum weight.
Pressure Actuated Backseat

The pressure actuated backseat provides maximum valve integrity by ensuring a positive
internal stop for the valve stem and disc assembly while extending packing life by securely
isolating the packing from line pressure when the valve is fully open.
Modular Body Styles

Three interchangeable body styles, Y, ANGLE and T-PATTERN use identical replacement
trim parts to lessen your tool and inventory costs. Solid cobalt alloy seats provide
high erosion resistance and repeatable in-line resurfacing (Cobalt free alloys are also
available).
Rapid In-line Serviceability

No other severe service globe valve offers the exceptional in-line serviceability provided by
our patented, modular Clampseal Globe Valves. The result? Enormous savings in downtime
and maintenance labor, plus reduced man-REM exposure in nuclear environments.

Swivldisc Gate Valve with bypass
Swivldisc® Gate Valves
• Integral Gland Wrench
• In Line Repairable
• Adaptable for Air or Motor Actuators
The Conval CLAMPSEAL® Swivldisc Gate Valve delivers

performance at the standard set by the legendary CLAMPSEAL®
Globe Valve.
The Swivldisc wedge gate design employs a flexible disc
face which permits the seating surfaces to achieve perfect
alignment, establishing a leak tight seal not possible with
standard wedge gates.
The simple and effective CLAMPSEAL® 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.
The Conval packing system delivers the best performance
available. The one-piece gland with integral gland wrench is
readily adjustable at anytime. Repacking can be accomplished
by swapping the bonnet-chamber with the fresh pre-packed
unit. The fine finish of the stem and chamber combines with
high performance graphite packing to ensure long packing
service life.
Selection of the CLAMPSEAL® Swivldisc is a commitment to
quality and best value.
Conval’s Swivldisc is the gate valve of choice when performance
must be assured in the most demanding services.
• Swivldisc gate
• Pressure Seal Bonnet
• High Performance Graphite Packing

Each Whisperjet section has four or six orifices around its perimeter. The recirculation control
orifices discharge inwardly, allowing the flow streams to impinge on each valves with Conval

velocity and sound level are minimized. Because the competitor valves’ control velocity type trim limited
mass flow and was causing the feed pumps to overheat. Today,
the Clampseal/Whisperjet valves are still operating flawlessly and

Special Application Valves
The CLAMPSEAL® design is uniquely suited to a number of special applications where service demands require rugged construction while
retaining easy in-line serviceability. No other forged valve offers this variety of applications.
Tandem Blowdown
Traditional bottom blowdown service requires a tandem valve. Unlike older massive designs with limited
serviceability, the CLAMPSEAL® unit tandem valve offers compactness, lighter weight and easy maintainability as
well as longevity of service.
Specifications:
Size/Style: 1” - 2 1/2” Material: SA 105
Class: ASME to 4500 SA 182-F22
End: Socket Weld, Butt Weld, Clamp Connector Example: 1.00-12B8HJ-105
Cryogenic Service
High pressure cryogenic service demands special attention to design and quality of material and fabrication.
The CLAMPSEAL® delivers tight shutoff and operability through a wide temperature range and meets
ANSI B 31.3 requirements.
Specifications:
Size: 1/2” - 4” Temperature: To -320ºF
Class: ASME 1500 and 2500 Material: SA 182-316

Three-Way Service
Conval has responded to the need for a high pressure, high temperature 3-way valve with easy serviceability for both
seats. Excellent service history and versatility make the CLAMPSEAL® valve the choice for 3-way service.
Specifications:
Size: 1 1/2” - 3” Material: Carbon Steel: (WCB)
Class: ASME to 2500 Low Alloy: (WC9)

Clampseal® Custom End Connections
Custom, extended end connections can simplify the retrofitting of Clampseal
valves to replace other manufacturer’s Y-pattern valves.
For applications with F91 material, extended end connections enable welders to
cut back to “virgin” pipe as required.
For applications with Post Weld Heat Treat (PWHT), extended end connections
allow for welds further away from the seat.

ASME Class and Ratings
ASME B16.34 incorporates socket weld end valves and butt weld end valves with Limited Class ratings. Conval offers the
industry’s finest forged steel globe valve with the highest ratings available. ASME Limited Class Rating applies to 2 1/2”
and smaller valves only and allows use of ASME Special Class Tables without NDE.
Standard Class Nominal Ratings

Standard class is a general use classification which uses the The ASME B16.34 tables list nominal ratings, i.e., 1500, 2500,
ASME Standard Class pressure temperature tables from B16.34. 4500. The actual class number (1500) leads to a table or graph

The Conval Story
In 1962, Mr. Chester Siver completed designs for a revolutionary line of
high-pressure, forged steel valves. Hamilton Standard (now UTC Aerospace
Systems), a division of United Technologies Corporation, was asked to use their
then-new Electron Beam Welding technology for joining of parts into valves for
subassemblies. Hamilton Standard became intrigued with the valve as an
ideal application of the Electron Beam Welding technique, and negotiated a
contract for the rights to manufacture and sell the valve. Mr. Siver served as
manager of the valve project.
The first CLAMPSEAL® valves were introduced to the market by Hamilton Standard
in 1964. However, in the mid-1960’s, growing demand for the firm’s popular aerospace
products forced Hamilton Standard to make the decision to abandon its industrial products.
The rights to the CLAMPSEAL valve reverted back to Mr. Siver. Since CLAMPSEAL valves were born in Connecticut, Mr. Siver founded
“Conval” (short for Connecticut Valve) in 1967. Today, the valves are still manufactured in Connecticut, a state with a longstanding
reputation for technological innovation and manufacturing excellence.
