SV615安全阀:全行程、全喷嘴安全阀。适用于蒸汽、空气不起化学作用的工业气体和非危险液体的应用。用于蒸汽或热水锅炉，发生器、压力容器、储气罐和空气压缩机，高压釜减压阀的下游保护等。

口径DN15~50，压力PN25,螺纹BSP或NPT连接，对于DN15~25可提供卫生级卡箍连接。密封性能符合API527标准。可提供软密封阀芯。SV607/SV604安全阀:全行程法兰连接安全阀。主要应用于蒸汽锅炉管道。压力容器、压缩机和储气罐等的防护及大多数的工业过程设备的防护。

符合DIN320 TRD421的要求，具有TUV认证，口径DN20~DN150，SV607压力级为PN16/25，SV604为PN40/AN300，可提DIN标准法兰和ANSI标准法兰。密封性能符合API527标准。根据客户要求可提供软密封阀芯。

    英国斯派莎克安全阀设计*，品种齐全，材质广泛(青铜、球铁、碳钢、合金钢、不锈钢等材质)，使用温度范围广泛，所有产品均有机构的认证。，能提供符合不同标准要求的安全阀。

在减压站系统中，为了防止减压阀下游压力高于设备运行的额定压力，减压阀下游必须安装安全阀。安全阀的设定压力必须在设备运行的zui大许可压力范围内，并与正常的运行压力间有足够的压差，以防止安全阀频繁起跳导致密封面损伤。安全阀的设定必须由有资格人员来进行。在安全阀选型时，应保证安全阀在设定压力下能通过减压阀所能流过的zui大流量。

 Introduction

    SV615 whole trip , the whole nozzle valve for steam, air , application role can not afford chemical inert industrial gases and non- hazardous liquids.

Application

SV615 safety valve : the whole trip , the whole nozzle valve . Suitable for the application of steam , air can not afford chemical industrial gases and non- hazardous liquids . For steam or hot water boilers, generators , pressure vessels , gas tank and air compressor , autoclave valve downstream protection.

Diameter DN15 ~ 50, the pressure PN25, BSP or NPT threaded connections DN15 ~ 25 provides for sanitary clamp connections . Sealing performance meets API527 standards. Provides a soft seal spool . SV607/SV604 safety valve : full stroke valve flange connection . Mainly used in steam boiler pipes. Pressure vessels, compressors and cylinders and other protective guard and most of the industrial process equipment.

Comply with the requirements of DIN320 TRD421 with TUV certification , caliber DN20 ~ DN150, SV607 pressure level is PN16/25, SV604 is PN40/AN300, can provide standard flanges and ANSI standards DIN flanges . Sealing performance meets API527 standards. According to customer requirements to provide a soft seal spool .

    Spirax Sarco advanced valve design , full range , the material widely ( bronze, ductile iron , carbon steel, alloy steel, stainless steel and other materials ) , widely used in the temperature range , all products are certified authority . To provide a safety valve meets the requirements of the different standards .

In the vacuum station system, in order to prevent the rated pressure relief valve downstream pressure is higher than the equipment operation , valves must be installed downstream of the valve . Pressure relief valve must be set within the maximum allowable operating pressure range of the device between the normal operating pressure and there is enough pressure to prevent the valve sealing surface damage resulting in frequent jump . Relief valve setting must be performed by qualified personnel. When the safety valve selection should guarantee the safety valve set pressure through the valve can flow through the maximum flow .

The following parameters:

1 , system or equipment must displacement and the proposed number of valves installed .

2, the opening pressure ( or set pressure )

3 , and the proportion of medium (liquid medium ) or molecular weight and compressibility factor ( for gaseous media )

4, the valve inlet medium temperature

5 , if there is back pressure , if any, is the number

6 , requires valve performance standards ( eg no special specified , specified by the supplier
