Data Sheet

Shut-off valve
Type SVA DH and
SVA DL 250 – 300

Designed to meet all industrial refrigeration application requirements

SVA-DL and SVA-DH are angleway shut-o
valves designed to meet all industrial
refrigeration application requirements.

SVA-DL (Delta pressure Low)

is designed with a restriction in the opening
function. High dierential pressure can be
applied from the side port and reduced
pressure can be applied from bottom port.
SVADL is a twostep valve for pressure relief.

SVA-DH (Delta pressure High)

is designed without restriction in the opening
function. As a result of its balanced design this
valve is able to open at
all dierential pressures with limited torque.
The angleway shut-o valves are carefully
designed to give favourable ow
conditions. Easy to dismantle for inspection
and repair.

Both SVA-DL & SVA-DH shut-o valves have
internal backseating enabling the spindle seal
to be replaced with the valve still under
pressure.

The valves are designed to give favourable ow
characteristics and are easy to dismantle for
servicing. The valve cone is designed to ensure
perfect closing.

Shut-o valves, Type SVA DH and SVA DL 250 – 300

Functions

SVA-DL

The SVA-DL shut-o valve is designed with a restriction in the ow direction (dierential pressure). To ensure the
most favourable valve performance the ow must be directed from the side port towards the valve cone. Operation
of the valve with ow in this direction is made possible by the two-step opening valve cone as illustrated below.

SVA-DH

The SVA-DH shut-o valve is designed without restrictions in either ow direction or dierential pressure. Due to
the balanced valve cone design the torque required to operate the valve is minimized and the valve can be opened
and closed against high pressure with ow in any direction.

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the
refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic
refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.

Product specication

Pressure and temperature

Figure 2: Pressure and temperature graph

Table 4: Pressure and temperature

Design

Housing and bonnet

Made from special, cold-resistant steel approved for low temperature operations.

Bolts

Stainless steel, Quality A2-70.

Valve cone assembly

The valve cone assembly is turnable on the spindle, thus there is no friction between cone and seat when the valve
is opened and closed. A Teon tightening ring provides perfect sealing at a minimum closing torque.

Spindle

Made of polished stainless steel, ideal for O-ring sealing.

Packing gland

The packing gland comprises a spring loaded seal packing which ensures perfect tightness in the range: -60 °C –
150 °C (-76 °F – 302 °F). Furthermore, the packing glands incorporate a scraper ring to prevent the penetration of
dirt and ice.
