Gauge Valves

We want to optimize our efficiency when it comes to helping our customers, and one way to do that is to stock standard products for immediate shipping. Our standard Gauge Valve models include the 10S and 20S, available in a variety of sizes and materials.

150514Img11647Our 10-TU valves feature a straight type body with integrated seat and Elastomer (EPDM), a glass tube packing bush with integral seat, and PTFE valve cone.

These are primarily used for tubular type level gauges, for low pressure and temperature applications. They are equipped with mounting clamps to t glass protection rods. They also feature a ball check arrangement.

Gas Lift Systems

It’s important to us that our customers get the best possible results with every project they execute. And we know that helping you achieve that is one way to keep you coming back to us! As part of our promise to help you maximize production, we bring you Gas Lift Systems as part of our Energy Equipment Division.

Gas lift systems are used to reduce the density of fluids in tubing, in order to extract more oil from a well. They use an artificial lift technique that adds vaporous bubbles to the fluid, in order to reduce the hydrostatic pressure in the outlet tube compared to the pressure on the inlet side of the tube.


In petroleum, gas is injected through the outlet tube into the fluid in order to aerate it, reducing the density and increasing the formation pressure. The increased pressure is able to lift oil column and move the fluid out of the wellbore. The gas can be injected intermittently or continuously, depending on the characteristics of the well.

Float Failure Indication

For us here at Bliss, your project’s safety is front and center. We know you can’t afford losses of your process materials, so we’ve built Float Failure Indicators onto our gauges, so that you can visually tell if something is wrong.

Screen Shot 2017-04-06 at 3.23.06 PM.jpg


As a standard feature on all our gauges, the bottom three flags are set in reverse. If these flags flip to the regular color, it will provide you with a visual indication of float failure. If this happens, you can immediately turn off your isolation valves and call us for a replacement float.

PTH Diaphragm Seals

Screen Shot 2017-03-07 at 1.56.46 PMPTH Diaphragm Seals were designed as an alternative to the existing Rosemount High Process Temperature Transmitter. The seal, which can be directly mounted onto a transmitter without the use of remote seals or capillaries, can go up to temperatures as high as 392°F (200°C), though by using different fill fluids the temperature can go even higher, up to 788°F (420°C). This solution makes it possible to measure differential or gauge pressure at high process temperatures through a direct mounted seal.

The PTH Seal is designed and manufactured to meet the requirements of IEC 61518, with all the wetted parts constructed from AISI 316 (L).



Maximum Temperature
Using BSO-22, the maximum process temperature it can withstand is 392°F (200°C). In combination with other filling fluids, the maximum process temperature can increase to 788°F (420°C).

Maximum Static Pressure

  • 200 bar / 392°F (200°C)
  • 250 bar / 68°F (20°C)
  • 350 bar / 68°F (20°C) (design)

Reference Accuracy
0,025% for the Diaphragm Seal + transmitter specifications

Mounting Position Effects
Zero shifts up to 15 mbar (at 180°C), which can be calibrated out. There is no span effect.

The PTH dimensions are designed according to the IEC standard 61518 and the seal is suitable for mounting to the process connectors according the DIN19213 1982 part 2 for manifold mounts.

Special Materials and CoatingsScreen Shot 2017-03-07 at 1.58.26 PM
The PTH Seal can be supplied with various exotic
diaphragm materials, including Hastelloy C276, Monel or Tantalum. The process flanges can also be supplied with these exotic materials. Other materials are available on request.

For Hydrogen applications, the PTH Seal Diaphragm can be Gold Coated.

Gold Coated Diaphragm Seals

Hydrogen is not typically considered corrosive, but as a common element in diaphragm seal applications, there are certain circumstances where it may cause issues. For these times, Bliss Anand America and Badotherm Netherlands offer you a solution – Gold Coated Diaphragm Seals. The gold protects the fill fluid from becoming saturated with hydrogen, leading to more accurate measurement for your project.

So what is hydrogen permeation?

Hydrogen is usually found is a diatomic state, as two hydrogen atoms, or H2. These molecules do not permeate a regular sized diaphragm, at a standard thickness of 75 μm. However, under certain pressures and temperatures, the diatomic hydrogen splits into two H+ ions that are smaller than the space between the molecules of the material used to construct a regular diaphragm. This allows the H+ ions to slip between the cracks. Having permeated the diaphragm, the H+ icons join back into H2, dissolving into, and eventually saturating, the fill fluid. Over time, hydrogen gas bubbles form, altering the performance of the mounted transmitter.


The Bliss Anand America – Badotherm Netherlands Solution

Gold is a noble metal, which means it is more resistant to corrosion than most other materials. Adding a layer of gold to a base metal provides an extra layer of protection to the seal. The H+ ions are not able to permeate the gold diaphragm foil, allowing your fill fluid to remain pure.


We take our seals the extra mile beyond our competition, and for increased security at extreme conditions, we offer 40µm thickness that can withstand temperatures up to 752 °F (400 °C). This design is approved by international end-users including Royal Dutch Shell.

Gold also increases the chemical resistance of the seals, and can therefore be used in multiple ways:screen-shot-2017-02-06-at-12-42-40-pm

  • To protect against hydrogen permeation, as described above, only the diaphragm is coated.
  • To increase chemical resistance, the coating can be extended to the outside diameter of the gasket surface.
