Specifications:
The document details specifications for streamlined flow valves and sediment collecting strainers. Valves include types with outside and inside screws with bellows, and check valves with springs, made from materials like nodular cast iron EN-GJS-400-18-LT and cast iron EN-GJL-250, with stainless steel components. Strainers are available in cast iron, nodular cast iron, carbon steel, and stainless steel. Both valves and strainers have maximum working pressures from 16 to 40 bar and temperatures from -10°C to +400°C.

Procedures:
Installation instructions for valves specify reverse installation for those with balanced discs when pressure is on the disc. Strainers can be equipped with special filtration screens upon request, with pressure ratings of PN16, PN25, and PN40.

Standards and Norms:
Valves conform to pressure norms PN 16 and PN 25, with color codes RAL 5013 and RAL 7001. Strainers meet standards such as EN-GJL-250, EN-GJS-400-18-LT, ASTM A 105, and AISI 316L, ensuring material quality and reliability.

Recommendations:
For valves, the use of regulating discs, soft sealing discs, and piezometric connections is recommended. For strainers, stellited seats are suggested for carbon steel and stainless steel valves, also available for cast iron and nodular cast iron valves from DN15 to DN50.

Key Data from Tables:
Tables provide dimensions (DN, D, L, H, V), weight (Kg), and flow coefficient (Kv) for valves and strainers. Kv values are given for fully open valves and at various stroke rates, with strainer sizes ranging from DN15 to DN300.

Critical Information:
- Maximum pressure and temperature limits for each valve and strainer type.
- Material specifications for components.
- Installation and operational guidelines for balanced disc valves.
- Variants available for different pressure and temperature requirements.
- Compliance with material standards ensures performance and safety in industrial applications.
