DRV30 self-operated pressure regulating valve

DRV30 self-operated pressure regulating valve

The self-operated pressure regulating valve is an ideal energy-saving product. It is widely used for the pressure retention and stability of steam. (Before the valve) automatic control.

  • DRV30 Product model: DRV30
  • DN 20-300 mm Specifications: DN 20-300 mm
  • 6.4 MPa(64Barg) Maximum allowable pressure: 6.4 MPa (64Barg)
  • 350℃ Maximum allowable temperature: 350 ℃
  • 直通型 Structure: Through type
  • 铸钢、不锈钢 Body material: cast steel, stainless steel
  • 法兰 Connection method: flange
  • GB Connection standard: GB
  • 非腐蚀性液体、气体和蒸汽 Use medium: non-corrosive liquid, gas and steam

The self-operated pressure control valve consists of a control valve, an actuator and a spring that sets the pressure. Suitable for non-corrosive liquids, gases and steam, pressure control before or after the valve in the system pipeline.
The self-operated pressure control valve itself is a regulating system. The valve itself has certain pressure drop requirements. For the pressure regulating valve behind the valve, in order to ensure that the pressure behind the valve is within a certain range, the pressure before the valve must reach a certain value.
Structural features <br /> No need for any external energy adjustment to save energy, sensitive pressure adjustment, good sealing performance After valve adjustment, pressure reduction and pressure regulator adjustment, pressure relief and pressure stabilization, sensitive pressure fluctuation

Regardless of the packaging method, the principle is to protect the steam self-operated pressure regulating valve from damage.
1. Packaging method Packaging materials for finished products are sacks, woven bags, wooden boxes or pallets. Which packaging material is used is determined by the contract or by the sales department based on the specific situation of the product, such as specifications, quantity, etc.
2. Packaging requirements The warehouse clerk shall perform delivery inspection in accordance with the "Product Delivery Sheet" and "Final Inspection and Test Operation Specifications" before packaging, and confirm the packaging before packaging.
Sack or woven bag
a Single packaged valve product should be packed in a bag of appropriate size, and then tied and tied with a rope;
b The outside of sacks and woven bags should indicate the arrival, delivery unit, product name, model, specifications, and number of this batch.
应有产品合格证,产品检验报吉(合同注明),材料质量证明书,产品说明书(合同注明)等相关技术文件。 c When the valve leaves the factory, each steam self-relief pressure reducing valve shall have relevant technical documents such as product certification, product inspection report (specified in the contract), material quality certificate, product manual (specified in the contract) and other related technical documents.
Wooden packing
a Before packing the valve, carefully check whether the model, specifications, quantity and certificate of compliance with the packing list.
b Single product packed in wooden cases. For heavier, medium-sized products. When packing, use foam or other methods to prevent the product from shaking.
c Multiple products packed in wooden cases. For small size, light weight and large number of products. Fill with foam or other soft materials when packing to prevent the products from colliding with each other during transportation.
d The iron box should be used around the wooden box to prevent the wooden box from being damaged during transportation.
e Each box should be accompanied by relevant technical documents such as the product certificate, packing list, product inspection report (specified in the contract), material quality certificate (specified in the contract), product specifications (specified in the contract), and fixed in the box Somewhere.
f The shipping marks outside the wooden box (address of consignee, address of consignee, consignor, etc.) should be neatly written and clear.
