DAPRV PRESSURE REDUCING VALVES

The DAPRV series pressure reducing valves are undergoing technical improvements and have undergone new certification. These stainless steel valves are suitable for steam, liquid and gaseous media, have a pressure-balanced plug and any instability of the inlet pressure does not affect the outlet pressure, which corresponds to the value in the control chamber. The great advantage of the technical solution is the fast and accurate response. The valves are certified for WRAS (UK) and ACS (France) and are ideal for drinking water, beverage and food production technologies. Installation of valves in the pipeline is possible in horizontal and vertical position.

ADVANTAGES OF USING THE SAFETY VALVE IN COMBINATION WITH A RUPTURE DISCS

The standards allow the use of a rupture disc both at the inlet and at the outlet of the safety relief valve. The combination of rupture disc and safety valves is becoming increasingly popular due to user benefits such as:

• Optimal leak tightness
• Increased operating pressure
• Extended valve life
• Reduced valve maintenance
• Improved corrosion resistance
• Viscous media compatibility
• Increased reliability

REALIZED PROJECTS

ETHYLENE STORAGE

Design, construction work, production and supply of controls for 3-eccentric Vanessa butterfly valves with single-acting pneumatic actuators. Sets of cryogenic and standard variants of valves will be used in the process of ethylene storage at the Slovnaft refinery in Bratislava.
