APV1. General Terms
This instruction manual should be read carefully by the competent operating and maintenance personnel.
We point out that we will not accept any liability for damage or malfunctions resulting from the non-compliance with this instruction manual.
Descriptions and data given herein are subject to technical changes.
2. Safety Instructions
Danger!
- Before any maintenance of the valve, the line system must be depressurized and drained if possible.
- Observe Service Instructions to ensure safe maintenance of the valve.
3. Mode of Operation
The DELTA VPN valve is used in places at which the reflux into the pipelines must be prevented. The valve opens through the pressure of the liquid against the spring-loaded valve disc.The closing process is introduced by the preloaded spring when the liquid flow into the flow direction stops.

4. Installation
- The VPN should be installed in vertical position with flow direction from the bottom to the top. In other installing positions, proper closing and/or emptying is not provided.
- For the valve design with two weld ends (DIN and ISO) a separate connection (e.g. clamp connection) must be provided in the continuing pipe system.
- The 1CL 2S version is already equipped with a clamp connection at the supply side so that the pipeline must also be provided with a clamp flange.Attention! Observe welding instruction.
4.1 Welding instructions
VPN
- Before welding, the guide with seal and the valve disc with spring must be dismantled from the housing.
- Welding should only be carried out by certified welders (DIN EN ISO 9606-1). (Seam quality DIN EN ISO 5817).
- The welding of the valve housings must be undertaken in such a way that the valve body is not deformed.
- The preparation of the weld seam up to 3 mm thickness must be carried out as a square butt joint without air. (Consider shrinkage!)
- TIG orbital welding is best! - After welding of the valve housing or of the mating flanges and after
work at the pipelines, the corresponding parts of the installation and pipelines must be cleaned from welding residues and soiling before operation of the valves to avoid damage to the valves and seals. If these cleaning instructions are not observed, welding residues and dirt particles can settle in the valve and cause damage.
- Any damage resulting from the non-observance of these welding instructions is not subject to our guarantee.

- Housing, valve disc, guide, cover: 1.4571, 1.4404 (DIN EN 10088)
- Clamp: 1.4301 (DIN EN 10088)
- Spring: 1.4436 (DIN EN 10088)
- Seal standard design: EPDM
8. Maintenance
- The maintenance intervals depend on the corresponding application and are to be determined by the operator himself carrying out temporary checks.
- Stock keeping by the customer of certain spare seals is recommended. For the valve service we supply complete seal kits..
- Exchange of seals is done according to service instructions - All seals must be provided with a thin layer of grease before
their installation. Recommendation:
APV assembly grease for EPDM (750 g / tin - ref.-No. 000 70-01-019/93; H147382) (60 g / tube - ref.-No. 000 70-01-018/93; H147381)
Do not use grease containing mineral oil for EPDM seals!
- Assembly of valve see Service Instructions.
