Brief introduction

DCV2 and DCV3 disc flange on the folder for the installation of check valves , can be widely used in process piping , hot water systems, steam and condensate systems in a variety of fluids , connection dimensions comply with EN558 Part1, Series49.

Standard products for the metal seat for steam systems. When used in the oil , air, gas , and water valve seat can be selected for other materials .

Owner: Wafer Check Valve is not suitable for severe pulsating occasions, such as compressors.

DCV series check valves compact structure , easy to install. Can be installed in vertical or horizontal pipe or inclined pipelines , simply two flanges on the folder to install.

DCV check valve for steam and a variety of liquids, gases and other industrial systems , and provides various options depending on the application :

Seat options:

metal seat (metal): - suitable for steam or other high temperature fluid systems .

Temperature range -200 ℃ ~ 400 ℃.

Rubber seat (Viton): - applies to oil and gas systems , to ensure a good seal .

Temperature range -15 ℃ ~ 250 ℃.

EPDM seat (EPDM): - for water systems.

Temperature range -50 ℃ ~ 150 ℃

Spring options:

Standard spring - with a dry steam, water and many other industrial fluid system .

Nickel-chromium alloy spring - for high temperature systems.

Strong spring - for boiler feedwater system .

No springs - for low flow pressure loss system . only for vertically upward flow in the pipeline .

DCV2和DCV3为碟片式法兰对夹安装止回阀,可广泛应用于过程管道、热水系统、蒸汽和冷凝水等系统中的各种流体,连接尺寸符合EN558  Part1,Series49。

标准产品为金属阀座,用于蒸汽系统。当用于油、空气、气体和水系统时可以选用其他材料的阀座。

主:对夹式止回阀不适合用于有严重脉动的场合,比如压缩机。

DCV系列止回阀结构紧凑,安装简便。可安装在垂直或水平管道或倾斜管道,只需简单的两片法兰对夹安装即可。
