Fisherr YD and YS Control Valves
Fisher YD and YS three-way cage-guided valves are
designed for throttling or flow-switching (on-off)
service, and are available in the following
constructions:
YD (Balanced)–For general converging (flow-mixing)
and diverging (flow-splitting) service. Available in
standard and high-temperature versions (see figure 1).
YS (Unbalanced)–For general converging service.
When used in diverging service, recommended for
on-off applications only (see figure 1).
The Fisher YD and YS product lines are available for a
wide range of applications, including sulfide and
chloride stress-cracking environments common to the
oil and gas production industries. To discuss available
constructions, contact your Emerson Process
Management sales office and include the applicable
codes and standards required for these environments.

Features
Economy--Balanced valve plug construction in the
YD permits use of smaller, lower-cost actuators. A
single one-piece valve accommodates both trim
designs and uses Fisher easy-e™ bonnets, gaskets,
and packing, thus cutting spare part inventory
costs.
Application Flexibility--Multipurpose capability
results from a valve designed specifically for
three-way control. A variety of valve sizes, end
connections, port diameters, and trim materials
provides design versatility for your control needs.
Excellent Sealing Capabilities--The ENVIRO-SEAL™
packing system option is available. This packing
system provides excellent sealing, guiding, and
loading force transmission.Theimprovedsealingof
the ENVIRO-SEAL system can help control emissions
to below the EPA (Environmental Protection
Agency) limit of 100 ppm (parts per million) from
W7593
Fisher YD Valve with 667 Actuator
valves. The ENVIRO-SEAL packing systems feature
PTFE, Graphite ULF, or Duplex packing with
live-loading for reduced packing maintenance.
Long Trim Life--Hardened trim materials provide
excellent wear resistance.
Easy Maintenance--Cage-type construction
simplifies inspection and removal of parts.
Parts Commonality--Packing parts, including
packing flange, studs and nuts, and packing kits, are
common to the YD, YS, and Fisher easy-e control
valves.
Valve Plug Stability-- Rugged cage guiding provides
high valve plug stability, which reduces vibration
and mechanical noise.

operational life and reliability of these systems also
reduce your maintenance costs and downtime.
For applications requiring compliance with
environmental protection regulations, the unique
ENVIRO-SEAL packing system (figure 5) and, for
hazardous service, the ENVIRO-SEAL bellows seal
system (figure 4) are offered. The emission control
packing system keeps emission concentrations below
the EPA 100 ppm requirement.
For an excellent stem seal in applications that are not
environmentally sensitive, the HIGH-SEAL Graphite
ULF packing system (figure 5) is offered. The
HIGH-SEAL packing system provides excellent sealing
at pressure/temperature ratings beyond ENVIRO-SEAL
limits. ENVIRO-SEAL systems may also be applied for
excellent stem sealing in higher pressure/temperature
applications not requiring EPA compliance.
ENVIRO-SEAL packing systems, available with PTFE,
Graphite ULF, or Duplex packing, and the HIGH-SEAL
Graphite ULF packing system feature live-loading and
unique packing-ring arrangements for long-term,
consistent sealing performance.
W5852-1
ENVIRO-SEAL, HIGH-SEAL
Packing Systems
ENVIRO-SEAL and HIGH-SEAL packing systems offer
excellent sealing capabilities. These systems easily
install i n your existing valves or can be purchased with
new valves. These systems help you seal your process
to conserve valuable process fluid. The long
Installation
Although YD and YS valves may be mounted with the
actuator in any position relative to the valve, the
normal position is with the valve in a horizontal run of
pipe and the actuator vertical above the valve. The
actuator should be supported in any position other
than vertical. Orient the valve so that valve plug
positions and flow directions will conform to the flow
indicator plate on the valve body.
Dimensions are shown in figure 8.
Note: For the NPS 8 high temperature construction,
thebottomflangeMUSTberemovedtoaccessand
remove the lower cage (see figure 2). BWE end
connections are not available for the NPS 8 high

1. Spring and bench sets selected for use with either 657 or 667. Other acceptable configurations possible from Fisher Specification Manager for a specific actuator type.
2. The bench set values shown assume an actual supply pressure to the actuator of 0 to 18 psig for a nominal 3 to 15 psig signal, an actual 0 to 33 psig supply for a nominal 6 to 30 psig signal,
and an actual 0 to 43 psig supply for a nominal 3 to 40 psig signal. Any positioner or controller used with these actuators must be capable of delivering the appropriate slightly extended range.
3. Requires non-standard spring adjustor.
4. Special Class IV seat load (40 lb/lineal inch) used for YD with 7-inch diameter port.

1. Spring and bench sets selected for use with either 657 or 667. Other acceptable configurations possible from Fisher Specification Manager for a specific actuator type
2. The bench set values shown assume an actual supply pressure to the actuator of 0 to 18 psig for a nominal 3 to 15 psig signal, an actual 0 to 33 psig supply for a nominal 6 to 30 psig signal,
and an actual 0 to 43 psig supply for a nominal 3 to 40 psig signal. Any positioner or controller used with these actuators must be capable of delivering the appropriate slightly extended range.
3. Requires non-standard spring adjustor.
4. Oversize yoke boss required.
5. Special Class 4 seat load (40 lb/lineal inch) used for YS, 7-inch port.

1. These in-body process temperatures assume an outside, ambient temperature of 21_C(70_F) and no insulation on the bonnet. When using any packing at low process temperatures, a cast
extension bonnet may have to be used to prevent the packing damage which could result from the formation of valve stem frost. Material selection for trim and other components will also be
limiting factors.
