The Bray Flow-Tek SRH Series spring-return manual operator is designed for ¼" to 2" ball valves and features an ISO 5211 mounting interface and stainless steel body. Releasing the handle automatically returns the valve to the closed position. A standard locking device maintains the required opening position, making it suitable for frequently operated manual points such as oil replenishment, process sampling, and equipment line draining.

Application scenarios

Refueling and Media Replenishment Stations

Suitable for refueling or media replenishment operations with compatible Flow-Tek ball valves. The spring-return handle is designed for frequent manual opening; releasing the handle returns the valve to the closed position. A locking device can hold the valve in the required position.

Process Line Sampling Points

Suitable for process sampling operations with compatible ball valves. Designed for frequent manual operations such as sampling, this handle forces the valve closed when released, reducing the risk of the valve remaining open after sampling.

Equipment and Pipeline Drain Branches

Suitable for equipment or pipeline draining operations with compatible ball valves. The spring-return handle is suitable for short-duration, intermittent manual opening and can lock the valve in the required position using the locking device.

OSHA Operating Points Requiring Manual Forced Closure

Suitable for OSHA applications requiring a manually operated valve to be forced closed when the operator releases the handle. The spring-return design automatically returns the valve to the closed position.

Selection points

Spring-Return Automatic Reset

Features a spring-return handle for applications such as filling, sampling, and draining where manual forced valve closure is required.

Standard Valve Locking Device

Each handle is equipped with a standard locking device to secure the valve in the required position.

Heavy-Duty Stainless Steel Construction

The manual actuator is constructed with heavy-duty stainless steel components for frequent daily manual operation.

ISO 5211 Direct Mounting for Compatible Flow-Tek Ball Valves

Available in three sizes for direct mounting on ISO 5211 mounting pads of compatible Flow-Tek industrial ball valves, suitable for 1/4 in. to 2 in. ball valves.

Retrofit for Existing Compatible Flow-Tek Lever-Operated Ball Valves

In accordance with the compatibility chart, the manual actuator can be retrofitted to existing compatible Flow-Tek lever-operated ball valves.

Paired with Live-Loaded Packing Valves

Compatible Flow-Tek valves use live-loaded packing, extending packing adjustment and maintenance intervals and reducing the need to remove the manual actuator during valve maintenance.

Installation & maintenance notes

Verify Valve Compatibility Against the Compatibility Chart Before Installation

When installing or retrofitting the SRH handle on an existing Flow-Tek ball valve, refer to the compatibility chart to confirm valve and handle compatibility. This series is suitable for compatible Flow-Tek full-port or standard-port industrial ball valves in sizes from 1/4 in. to 2 in.

FAQ

How does the SRH Series manual actuator work?

The SRH Series manual actuator uses a spring-return design that automatically returns the valve for rapid reset and secure positioning.

What valve sizes are compatible with the SRH Series manual actuator?

It is directly compatible with ¼" to 2" ball valves and mounts to an ISO5211 mounting pad, which is then connected to a Flow-Tek full-port or standard-port ball valve.

What is the function of the locking device on the SRH manual actuator?

The integrated locking device locks the valve in the required position for safe operation and positioning.

What are the key maintenance and packing considerations for the SRH manual actuator?

The live-loaded packing compatible with Flow-Tek valves extends packing adjustment and maintenance intervals, reducing the need to remove the manual actuator during maintenance.

How can an SRH manual actuator be retrofitted to an existing Flow-Tek valve?

Following the compatibility chart, each SRH manual actuator can be retrofitted to an existing Flow-Tek lever-operated ball valve.
