Designed for multi flange ratings and piping standards. * Available for ANSI 600# with adapter ring. Consult BS&B or your local representative. The Type TR™ Series torque resistant safety head option offers the identical performance and flow …

The EC-7RS™ Safety Head is designed with a unique metal-to-metal stop, preventing over torquing and consequential damage to the disk. Flow arrows indicate the direction of the process flow during venting.

HL-7RS and HL-7R safety heads are available in 316 stainless steel and carbon steel as standard. Alternative materials are available

The EC-7RS is designed with a unique metal-to-metal stop, preventing overtorqu-ing and damage to the disk. Flow arrows indicate the direction of process flow during venting. The safety head fits ANSI, DIN and JIS pipe flange bolting pat-terns in 316ss, carbon steel, aluminum, alloy 400, alloy 600, Hastelloy® C-276. EC-7RS Pre-Torqued Design

The CSR-7RS™ CSI-7RS™ pretorqued safety heads are designed to support the fail safe characteristics of the CSI reverse buckling disk. Both safety heads contain the energy absorbing hinge that aligns with an unscored portion of the CSI disk perimeter to retain the CSI disk upon opening, preventing frag-mentation. Features include:

The SRI-7RS™ is a pre-torqued safety head designed for ease of handling and installation. The BS&B signature ‘bite-seal’ is present in all nominal sizes, optimizing leak tightness.

SRB-7RS型ホルダー は現場での組立作業に先立ってショップ内で破裂板を組付けることができるプリトルク型のホルダーです。 これにより破裂板を前もって規定トルクで締め付けておくことができます。 実績のあるメタル噛込み式バイトシールにより気密シールが保証されます。 オフセットピンにより破裂板は正しい位置に容易に取付けることができます。 バイトシールによりメタルタッチで完全密封できます。 反転型破裂板はソリッドメタル設計ですのでバキューム …

Pour des pressions opératoires normales, en service gaz, opter pour n’importe quel type de disque du système STA-SAF™ associé à la monture-support SRB-7RS™. Pour les applications en service sur liquide, utiliser les disques RLS™, SKR™, LPS™ ou Sigma™, et le type RLS™ pour des pressions plus élevées.
