General Information

Overview

API 526 CC safety valves are flanged, spring loaded safety valves that meet all the requirements of API 526 standard such as orifices and center-to-face dimensions. Their robust construction makes them especially suitable for API market.

LESER’s API 526 CC Series safety valves present the perfect safe solution for heavy duty applications, such as crude oil extraction, transportation and processing in

· Refineries

· Chemical industry

· Petrochemical industry

· Oil and gas - Onshore and Offshore

· Vessels and piping systems

· Blow-down systems

· Storage tank farms

· Nonferrous metal industry, etc. alumina

LESER offers the full range of safety valves according to API 526 in China. Especially for the requirements ò the Chinese market - LESER API 526 CC that is based on these requirements in the following areas:

· Approvals (ASME UV and AQSIQ TS)

· Materials

· Fast delivery time, we can change our delivery time according to different customer requirements

Reliable valve function

Durable Design

· Bellows are calculated for extended operating cycles and protected against turbulences during discharge by the bellows shield

· Material combinations and surface treatment in guiding zones to avoid wear

· The body is designed to be self-draining to avoid residues

Durable Design ensures the long-term reliable function of the safety valve and can lead to extended maintenance intervals

Tight Finish

· Tightness better than API 527

· Optional soft seals for zero bubbles

For each application, there is a sealing concept to minimize medium loss and emissions

Low lifecycle costs

Single Trim

· Use of identical trim parts for gas, steam and liquid services.

· No change of trim parts is necessary when changing the use of the safety valve.

Reduced number of spare parts

Quick supply

Quick and reliable supply chains

Fast delivery time

Our factory in Wuqing has a high inventory with a state of the art production. Delivery times depend on customer needs: 1 week to 4 weeks.
