CRYOGENIC VALVE MANUFACTURERS IN GERMANY

Valvesonly Europe being one of the biggest Cryogenic valve manufacturers in Germany, is providing high-quality, reliable, and efficient cryogenic valves to industries that are dealing with liquefied gases at very low temperatures.
Chemical processing, medical gas, aerospace, and LNG (liquefied natural gas) are some of the sectors that employ cryogenic valves since they can operate at temperatures as low as -196°C. Leak-proof, strong, and safe to use, the valves are employed for liquid nitrogen, oxygen, argon, and hydrogen.

Why is it necessary?
Cryogenic valves have to handle gases and liquids at temperatures that are extremely low without losing efficiency. It is impossible to emphasize enough how important it is to maintain cryogenic fluid integrity for safety and successful operations across industries like space travel, medical gas storage, and processing of LNG. Because normal valves cannot function at such low temperatures, cryogenic valves that are specially made are required. Along with smoothly controlling flow and turning off during low temperature operations, these valves will stop freezing, cracking, and leaks.

Installation Manual:
Installation of cryogenic valves must be done correctly to provide efficient operation and safety. Follow these steps to install them properly:
Selection: Select the right valve size and type according to the intended cryogenic use.
Positioning: Mount the valve vertically to avoid damage from thermal expansion and contraction.
Insulation: Insulate the valve and adjacent piping properly to avoid frost formation.
Flange Connection: Utilize bolts and gaskets of cryogenic grade to have a good seal.
Pressure Testing: Perform pressure testing post-installation to inspect for any leakages and achieve proper sealing.

Working:
Cryogenic valves incorporate an extended bonnet that separates the cryogenic fluid from the actuator of the valve. This serves to prevent freezing and smooth out operations. Once a signal is received by the valve, the actuator is activated to shift the stem, which opens or closes the valve depending on the required flow. An extended stem acts to hinder the formation of ice on the actuator, promoting uniform operation regardless of extreme temperatures. Cryogenic valves are specially constructed to reduce heat transfer so that the fluid will not heat up and build pressure.

What is a Cryogenic Valve Herose:
Herose Cryogenic Valve is a high-performance, specially manufactured LNG, oxygen, nitrogen, and other liquefied gas valve. According to international safety standards, Herose is well known as a top manufacturer of cryogenic valves that are strong, reliable, and very efficient. All the shipping, processing, and cryogenic storage industries heavily utilize the valves.

Functions:
• Control the flow of cryogenic fluids and gases.
• Offer a tight seal to prevent leaks and pressure loss.
• Maintain consistent flow rates during low-temperature operation.
• Help prevent backflow and system contamination.
• Facilitate safety in high-pressure cryogenic systems.

Key Elements:
 Valve Body: Constructed with stainless steel or bronze for toughness.
 Extended Bonnet: Provides insulation from freezing cold temperatures.
 Sealing Mechanism: Employs PTFE or elastomer seals for proper closure.
 Stem & Actuator: Operates the opening and closing of the valve.
 Self-Relieving Feature: Automatically discharges excess pressure.
 Anti-Freeze Design: Avoids ice formation and system failure.

What types of cryogenic valves are there?
 Cryogenic Ball Valves: Deliver rapid shut-off and minimal pressure drop.
 Cryogenic Gate Valves: Appropriate for high-pressure operations.
 Cryogenic Globe Valves: Best suited for exact flow control.
 Cryogenic Check Valves: Stop backflow and ensure directional flow.
 Cryogenic Butterfly Valves: Light in weight and appropriate for large-diameter pipes.
