Niezgodka Type 75 Reducing Valve (Low Output Pressures)

**Comprehensive Testing and Recertification Service for Used NABIC Relief and Safety Relief Valves** At our company, we specialise in thorough testing and recertification services for used NABIC relief and safety relief valves. Our dedicated process begins with an assessment of your valve’s condition, during which we typically document its state through photographs. Following this initial check, we carry out the necessary tests and provide recertification for the valve. Should your valve require a spare parts kit, we will consult with you prior to proceeding with the testing and recertification. In the event that your valve is found to be beyond economical repair, you have the option to purchase a new valve, and we will deduct the cost of the original valve from the price of the replacement. **Important Information:** (a) If the label on the valve is illegible, please include a note specifying the required set pressure when you send the valve. (b) Pricing is determined by the inlet size of your valve. (c) Please note that you are responsible for the shipping costs to send your valve to us. (d) The carriage fee included at checkout will cover the cost of returning your valve to you after servicing. For efficient recertification and peace of mind, trust our expert team to ensure your NABIC relief and safety relief valves are in compliance with industry standards.

The CONCOA 212 Series is a five-port, chrome-plated forged brass, dual-stage cylinder regulator designed for primary pressure control of high-purity, non-corrosive, or liquefied inert gases (up to grade 4.5). Its dual-stage design ensures stable pressure and delivery regardless of supply pressure variations. Factory-configurable options include single-station manifolds, purge, low-pressure alarms, or multiple inlets.

### Refrigeration Shut-Off Valves for Industrial Systems Refrigeration shut-off valves are essential components in industrial refrigeration systems, designed to isolate specific sections during maintenance, repair, or troubleshooting. These valves enable swift control of refrigerant flow, allowing particular parts of the system to be safely shut off without disrupting overall operation. They are commonly employed in refrigerant cycles, ensuring efficient and effective management of refrigerants. #### Product Specifications - **Sizes:** Ranging from 1/4" to 20" (varies by type) - **Connections:** Available with flanged, screwed, butt weld, and solder options (depending on the type) - **Materials:** Constructed from durable steel or stainless steel - **Medium:** Suitable for glycol-based cold brine refrigerants according to EN 378 p. 1, including NH3, R134a, R290 (propane), R507, and blends with refrigerant oil, as well as neutral, gas, and liquid media - **Set Pressure:** Options include PS 25, PS 40, PS 63, and PS 160 (varies by type) - **Temperature Range:** Capable of operating between -60 to +150 degrees Celsius These refrigeration shut-off valves are designed to maximise efficiency and safety in your industrial refrigeration setup. For optimal performance and reliability, choose the right valve type that aligns with your system requirements.
