Kingbolt Valves and Control Service



Kingbolt Steel can supply safety valve, which provide protection from over-pressure in steam, gas, air and liquid lines. The valve “lets off steam” when safe pressures are exceeded, then closed again when pressure drops to a preset level.

General Design Features

Design fully in accordance with API 526 for easy interchangeability.

Complete API 526 range :
valve sizes 1″ through 8″ orifice D through T

Materials :
WCB, WCC, CF8M, Wc6, LCB, LCC, 1.0619 and a wide range of special materials to fulfill the requirements of critical applications. Fool proof design with fewer parts for built-in safety. Open or closed bonnet, packed or plain lifting lever or gas tight cap. Flanged connections according ASME guarantee a worldwide applicability.

One design and spring (single trim) for steam, gas and liquid applications reduces the number of spare parts and ensures low cost maintenance management.

One-piece spindle reduces friction which leads to high operation accuracy. Self-draining body design, avoids residues and reduces corrosion. Stellited or hardened metal stealing for longer product life. Soft seat solutions for superior tightness.

Safety valves present the simple safe solution for heavy duty application, 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.
