Type 12 Welded, Sanitary, Clamped-Style, ASME-BPE Diaphragm Seals
Type 12 Welded, Sanitary, Clamped-Style, ASME-BPE Diaphragm Seals
Key Features
- Features a flush mount diaphragm and all welded construction, ideal for food & beverage, pharmaceutical and sanitary markets
- Wetted parts and all welded housing are constructed of 316 stainless steel for
greater strength and durability - Minimum working pressure 0 to 30 psi through -30 inHg to 600 psig
- Accommodates process connection pipes from 1-1/2" through 3" sizes
- Accommodates 2-1/2", 4", 4-1/2" and 6" gauge sizes
- Clamped connection allows ease of installation and removal of seal for maintenance and cleaning
- Wetted materials polished to Ra 32 or better
- Consider gauge size, pressure range, media composition, ambient and operating temperature, and maximum working pressure when selecting
- For process temperatures over 212 °F a capillary or cooling element is recommended,
contact factory to order - Fill fluid must be compatible with process media; i.e. glycerine may become volatile
in conjunction with a strong oxidizing agent such as chlorine, forms of oxygen or
peroxide and nitric acids
Suitable pressure gauge sizes |
2-1/2", 4", 4-1/2 and 6" Will also operate with most transducers, transmitters and pressure switches |
Minimum span pressure | 30 psig |
Maximum working pressure | Maximum operating pressure is determined by the clamping device and piping system - Please consult factory |
Operating temperature | Refer to fill fluid expansion factors table |
Note: NOSHOK pressure transmitters or transducers are not to be
used in heat sterilization system as stated in 3A Standard 74-03 paragraph
