Product Description

Danfoss ammonia with stop valve (SVA-S80/100-200/148B5900)freon with stop valve 

product introduction

Danfoss SVA hand wheel Angle valve and bonnet type Angle valves, hand wheel pass valve and bonnet type valve

Overview: SVA globe valve with Angle type and leading type two kinds of valve seat, including the standard version (SVA -s) and long neck (SVA - L) two forms.

The cut-off valve is suitable for the areas of industrial refrigeration application, provides the best flow conditions, convenient for dismantling and easy to maintenance. Unique design makes the valve valve core has a reliable sealing performance, can withstand the high intensity of system vibration and suitable for refrigeration

Various piping system.

SVA cut-off valve features: suitable for all kinds of no flammable refrigerant (including ammonia) and no corrosive gas/liquid medium, suitable for co2 system. Can be used in chemical and petroleum chemical industry

S module concept:

Equipped with SVL series general seat, can be arbitrary replacement SVL piping components platform of various functional modules

S rapid convenient valve repair service, easy to change at the top of the function module without welding

S optional accessories:

- the handwheel to switch suitable for frequent operation

- the bonnet is suitable for the frequent switch operation

S divided into Angle type and leading type two kinds, including the standard version and facilitate the long neck version of insulation (DN 15 to 40) DN

S are clearly marked on each valve type, size and performance

S between the body and bonnet are easily use seal wire for seal globe valves in case wrong operation condition without permission

S internal metal back sealing function: - DN 6-65 (quarter - 2 1/2 level in.); Internal back of PTFE sealing function: 80-200 - DN (3-8 in.)

S two-way flow function design

S seat and bonnet material to conform to the requirements of the PED pressure equipment instructions and other international standards of steel at low temperature

S equipped with stainless steel screws

S maximum working pressure: 52 bar (754 psi, g) g

S temperature range: - + 60 ℃ / 150 ℃ (76 ℉ / + 302 ℉)

S authentication types: DNV, CRN, BV, etc

SVA right Angle type globe valve and SVA through type globe valve technical parameters:

The connection method

Provide the following connections:

S butt welding DIN (EN 10220)

S butt welding ANSI 36.10 wall thickness (B grade Sch 80), DN 6-40 (1/2 level fell - 1 in.)

S butt welding ANSI 36.10 wall thickness (B grade Sch 40), 50-200 DN (2-8 in.)

S socket (ANSI B 16.11), DN 15 - DN 50 (1/2 level - 2 in.)

S pipe external thread G 1/2 level in. - G in 7/8. 228/1 (ISO)

S FPT thread, NPT (ANSI/ASME B 1.20.1), DN 15-32 (1/2 level 1 quarter in.)

The valve body

Using special low temperature resistant steel.

The valve core

Can circuition valve core, so when the valve switch there is no friction between valve core and valve seat can protection valve plate from wear and tear. The valve core

The special design can make it in the open state from system vibration caused by rotary valve core. At the same time, teflon valve plate to make the valve in the closed with a reliable sealing performance.

The valve stem

Use polishing stainless steel, is very suitable for sealing seal.

Stuffing box

Low temperature can packing in the temperature range to ensure perfect closure - + 60 ℃ / 150 ℃ (76 ℉ - / + 76 ℉). Packing is equipped with scraper ring, can prevent the dust and ice into the packing. Pressure equipment directive (PED) : SVA cut-off valve pressure equipment directive in conformity with the provisions of this European standard, with the compulsory certification mark.

The installation

The flow of advice in the mark on the valve body for installation. SVA cut-off valve can also reverse installation, but the body of the Kv value (Cv) is affected by the minor. Body is can withstand higher internal pressure in the design, but on the whole system must be avoided effusion phenomenon occurring in a line, in order to reduce because heat expansion pressure impact. Detailed information please see the SVA installation instructions.
