Technology

Summary

Features:

• Superior Throttling Performance - The splined ball to

shaft connection, splined shaft to actuator connection,

double power-end bushing assemblies, and trunnion gui-

ding, all provide improved dynamic control.

• Aerodynamic Performance - Up to 20 dBA acoustical

attenuation can be achieved for the V260A within a

single stage construction. Dual-stage construction can

provide up to 25 dBA attenuation.

• Improved Service Life - The attenuator is an integral

part of the valve assembly. The seal wipes the ball surface,

not the attenuator, promoting increased service life.

• Trim Versatility - Key valve components, such as

valve body, ball, shaft and bearings, are interchangeable

between the Design V260A, V260B and V260C. This

feature allows you to reduce your spare parts inventory and

maintenance time.

• Sour Gas Service and Sour Crude Oil Capability - Optional

materials are available that comply with NACE

Standard MR0175.

• Tight Shutoff - Self-adjusting seal(s) that are pressure

assisted provide tight shutoff for longer reliable service.

The design incorporates a heavy duty S31600 stainless

steel carrier that retains the composition seal for fullrated

pressure drop service.

• Heavy Duty Trunnion - The ball trunnions are

designed for demanding applications requiring longer

service life, with a reduction in maintenance time

and costs.

• Broad Hydrodynamic Applications - Single, dual, and

three-stage attenuators for the V260B may be provided

for a varying range of cavitation applications. A Kc value

of 1.0 is achievable depending on service conditions.

• Flexible Applications - The attenuator is active throughout

the ball rotation for very demanding services or a characterized

attenuator is used to match the service conditions.

Operational Overview:

The Fisher V260 is designed for throttling service and differs

signiﬁcantly from typical ball valves developed as block

valves. Special attention is applied to the friction and shut-off

capability of the sealing mechanism to minimize stick-slip

on rotation (sticktion). Dimensions are controlled to create

a pressure assist to the lightly biased seat ring.Other major

features supporting the throttling design objectives are the

splined shaft to ball and splined shaft to actuator connections

that minimize lost motion. The rugged double drive bearing

concept and the opposite stub shaft bearing, control the

dynamic and shut-off forces unique to throttling applications.

The Design V260 is

a full bore control

valve designed from

the ground up with

features for

optimized pressure,

ﬂow and process

control. An integral

attenuator controls

noise and vibration

from high pressure

drop liquids and

gases. The splined

shaft connection to

the actuator

reduces lost motion.
